    In situ study of nickel formation during decomposition of chemical vapor deposition Ni3N films2010In: Journal of Vacuum Science & Technology. A. Vacuum, Surfaces, and Films, ISSN 0734-2101, E-ISSN 1520-8559, Vol. 28, no 5, p. 1203-1209Article in journal (Refereed)
    Abstract [en]

    The thermal decomposition of Ni3N thin films, deposited by chemical vapor deposition on SrTiO3 (001) and Si (100) substrates, has been studied by in situ x-ray diffraction, as well as temperature-programed controlled gas emission in both inert and hydrogen atmospheres. The decomposition at inert atmosphere conditions starts at the film/substrate interface, which results in a high degree of ordering in the formed nickel film. In the H-2 atmosphere, the initial film ordering is less pronounced and the decomposition occurs from the film surface and downward. This means that by choosing the annealing atmosphere, inert or hydrogen, the formation of the Ni film can be localized to either the original nitride/substrate interface or to the surface of the nitride. The annealed films show a cube-on-cube growth with respect to the SrTiO3 (001) substrate. The film morphology after the annealing experiments resembles the one of the as-deposited films. The lowest resistivity value is measured for the films annealed in the H-2 atmosphere. (C) 2010 American Vacuum Society. [DOI: 10.1116/1.3478298]

    Tribofilm formation from TiC and nanocomposite TiAlC coatings, studied with Focused Ion Beam and Transmission Electron Microscopy2009In: Wear, ISSN 0043-1648, E-ISSN 1873-2577, Vol. 266, no 9-10, p. 988-994Article in journal (Refereed)
    Abstract [en]

    This work demonstrate how two different carbide coatings respond very differently to tribological stress and their very different ability to provide low friction tribofilms in dry sliding against steel. Both coatings, TiC and TiAlC, were deposited by DC-magnetron sputtering, but while the TiC is a thermodynamically stable coating, the TiAlC is made metastable with the addition of Al, and therefore releases carbon upon tribological testing. Thus, the TiAlC coating is shown to be self-lubricating on the atomic scale which makes very low friction   achievable. The primary interest in this study is the differences in the tribofilms formed on the steel balls that have been sliding against  the two coatings. Cross-section samples for transmission electron  microscopy were extracted from the ball tribofilms using a focused ion beam instrument. X-ray photoelectron spectroscopy and Raman analysis were employed to provide information on the chemical and structural  characteristics of the tribofilms. It was shown that tribofilms on steel balls largely inherit the structure and composition that evolve   in the coating wear tracks, that the tribofilm microstructure greatly affects the friction level. It was also shown that tribofilm delamination, occurring with tribofilm growth, was initiated in weak ribbon like regions inside the tribofilm.

    Area selective laser chemical vapor deposition of diamond and graphite1997In: Applied Surface Science, Vol. 109, p. 462-466Article in journal (Refereed)
    Abstract [en]

    High quality diamond and graphite has been deposited area selectively on silicon substrates in a hot filament chemical vapor deposition reactor employing laser heating. A mixture of CH4 (1–3 vol%) and H2 was passed over a tantalum filament having a temperature of approximately 2200°C. A laser beam was used to raise the temperature locally on the substrate surface. By a proper choice of filament temperature, substrate background temperature and laser induced temperature, isolated islands of polycrystalline diamond or graphite could be deposited on the silicon substrate. The deposited diamond and graphite spots were characterized by micro-Raman spectroscopy, scanning electron microscopy and scanning force microscopy.

    On the growth mechanism of UV laser deposited a-C:H from CH2I2 at room temperature2001In: Applied Surface Science, Vol. 172, no 3-4, p. 200-206Article in journal (Refereed)
    Abstract [en]

    Hydrogenated amorphous carbon films have been deposited on tungsten and quartz substrates at room temperature by photolytic dissociation of CH2I2. An Ar+ cw laser operating at 350 nm was used as the excitation source. The laser beam was focused parallel to the substrate surface. The deposition process was investigated as a function of laser power and total pressure. The carbon films were analysed by micro-Raman spectroscopy, IR spectroscopy, atomic force microscopy, scanning electron microscopy and energy dispersive X-ray spectroscopy. The growth mechanism is discussed from results and analysis.

    Crystal and magnetic structure investigation of TbNi5-xCux (x=0,0.5,1.0,1.5,2.0): Experiment and theory2006In: Physical Review B. Condensed Matter and Materials Physics, ISSN 1098-0121, E-ISSN 1550-235X, Vol. 74, no 9, p. 094419-Article in journal (Refereed)
    Abstract [en]

    The effect of Cu substitution on the structural and magnetic properties of TbNi5-xCux (x=0,0.5,1.0,1.5,2.0) have been investigated by x-ray diffraction, magnetization measurements and neutron powder and single crystal diffraction. The electronic and the magnetic structures of TbNi5 were studied using first principles theory. All samples were found to have the CaCu5-type structure, space group P6/mmm. The lattice parameters increase monotonically with increasing Cu concentration. The Curie temperature T-c has a maximum value of 29 K at x=1.0. The magnetic structure of TbNi5 at 10 K is incommensurate with a helimagnetic component [wave vector q similar to 2 pi/c(0,0,0.02)] perpendicular to a ferromagnetic one. In contrast, the substituted TbNi5-xCux alloy is ferromagnetic. All magnetic moments are observed to be located on the Tb atoms. The magnetocrystalline anisotropy in the ab plane is observed to be strongly increased by the Cu substitution, whereas the magnetization decreases with the Cu concentration. The observed magnetic structure of TbNi5 is consistent with first principles calculations regarding both the magnetic moments and the helimagnetic structure. The microscopical origin of the helimagnet is analyzed and correlated to the Fermi surface topology.

    Micromechanical testing of carbon fibers deposited by low-pressure laser-assisted chemical vapor deposition2004In: Carbon, Vol. 42, no 14, p. 2905-2913Article in journal (Refereed)
    Abstract [en]

    Carbon fibers were deposited directly from ethylene by laser-assisted chemical vapor deposition. The precursor gas pressures and the incident laser powers were varied. Micro-mechanical testing was carried out using a high-precision micro-manipulator. During three-point bend testing the fibers showed an elastic response, with no residual strain upon unloading, until fracture. The fibers’ strength and Young’s modulus are reported. A model for fiber fracture is proposed based on fiber cross-section analysis. Scanning electron microscopy was used to study the fiber cross-sections and the fiber surface morphology. The mechanical properties are related to the characteristic fiber microstructure investigated by Raman spectroscopy

    Electronic structure and chemical bonding of nanocrystalline-TiC/amorphous-C nanocomposites2009In: Physical Review B Condensed Matter, ISSN 0163-1829, E-ISSN 1095-3795, Vol. 80, no 23, p. 235108-Article in journal (Refereed)
    Abstract [en]

    The electronic structure of nanocrystalline (nc-) TiC/amorphous C nanocomposites has been investigated bysoft x-ray absorption and emission spectroscopy. The measured spectra at the Ti 2p and C 1s thresholds of thenanocomposites are compared to those of Ti metal and amorphous C. The corresponding intensities of theelectronic states for the valence and conduction bands in the nanocomposites are shown to strongly depend onthe TiC carbide grain size. An increased charge transfer between the Ti 3d-eg states and the C 2p states hasbeen identified as the grain size decreases, causing an increased ionicity of the TiC nanocrystallites. It issuggested that the charge transfer occurs at the interface between the nanocrystalline-TiC and the amorphous-Cmatrix and represents an interface bonding which may be essential for the understanding of the properties ofnc-TiC/amorphous C and similar nanocomposites.

    Rhodanine dyes for dye-sensitized solar cells: spectroscopy, energy levels and photovoltaic performance2009In: Physical Chemistry, Chemical Physics - PCCP, ISSN 1463-9076, E-ISSN 1463-9084, Vol. 11, no 1, p. 133-141Article in journal (Refereed)
    Abstract [en]

    Three new sensitizers for photoelectrochemical solar cells were synthesized consisting of a triphenylamine donor, a rhodanine-3-acetic acid acceptor and a polyene connection. The conjugation length was systematically increased, which resulted in two effects: first, it led to a red-shift of the optical absorption of the dyes, resulting in an improved spectral overlap with the solar spectrum.Secondly, the oxidation potential decreased systematically.

    Combined Extraction and Electrochemical Detection of Amines and Phenols Using Microelectrodes in Organic Solvents2009In: Electroanalysis, ISSN 1040-0397, E-ISSN 1521-4109, Vol. 21, no 10, p. 1211-1214Article in journal (Refereed)
    Abstract [en]

    A straightforward approach for liquid-liquid extractive detection of aromatic amines and phenols is described based on the spontaneous transfer of the molecule from the aqueous to an organic phase and subsequent electrochemical detection in the latter phase using a microelectrode. It is demonstrated that the extent of the transfer can be modified by altering the pH of the aqueous solution and the organic solvent. It is also concluded that the presence of an ion-pair formation agent does not increase the transfer yield for 4-chloroaniline and phenol. The present approach combines liquid-liquid sample clean-up and quantification into a single step which significantly facilitates determinations of aromatic amines and phenols present in complex samples.

    Voltammetric Determination of L-Dopa on Poly(3,4-ethylenedioxythiophene)-Single-Walled Carbon Nanotube Composite Modified Microelectrodes2010In: Electroanalysis, ISSN 1040-0397, E-ISSN 1521-4109, Vol. 22, no 4, p. 449-454Article in journal (Refereed)
    Abstract [en]

    In the present communication, it is shown that platinum microelectrodes electrochemically coated with a composite of poly(3,4-)ethylenedioxythiophene and single-walled carbon nanotubes (PEDOT/SWNT) enable determinations of 3,4-dihydroxy-l-phenylalaines (L-dopa) in neutral phosphate buffer solutions containing an excess of ascorbic acid. The interpenetrated networked nanostructure of the composite was characterized by scanning electron microscope (SEM) and Raman spectroscopy. It is shown that the presence of the composite gives rise to an increase in the electroactive area of an order of magnitude in compared to the area for the bare microelectrodes. The composite film- coated microelectrode, which yielded reversible cyclic voltammograms for the ferro/ferricyanide redox couple for scan rates between 0.01 and 0.10 V s 1, also gave rise to two well-resolved oxidation peaks for l-dopa and ascorbic acid (AA). The latter effect, which was not seen in the absence of the composite, enabled differential pulse voltammetric determinations of l-dopa in the concentration range between 0.1 to 20 μM with a detection limit of 100 μM.

    Adsorption and Solar Light Decomposition of Acetone on Anatase TiO2 and Niobium Doped TiO2 Thin Films2006In: Journal of Physical Chemistry B, Vol. 110, no 3, p. 1210-1220Article in journal (Refereed)
    Abstract [en]

    Adsorption and solar light decomposition of acetone was studied on nanostructured anatase TiO2 and Nb-doped TiO2 films made by sol-gel methods (10 and 20 mol % NbO2.5). A detailed characterization of the film materials show that films contain only nanoparticles with the anatase modification with pentavalent Nb oxide dissolved into the anatase structure, which is interpreted as formation of substituted Nb=O clusters in the anatase lattice. The Nb-doped films displayed a slight yellow color and an enhanced the visible light absorption with a red-shift of the optical absorption edge from 394 nm for the pure TiO2 film to 411 nm for 20 mol % NbO2.5. In-situ Fourier transform infrared (FTIR) transmission spectroscopy shows that acetone adsorbs associatively with 1-coordination to the surface cations on all films. On Nb-doped TiO2 films, the carbonyl bonding to the surface is stabilized, which is evidenced by a lowering of the (C=O) frequency by about 20 cm-1 to 1672 cm-1. Upon solar light illumination acetone is readily decomposed on TiO2, and stable surface coordinated intermediates are formed. The decomposition rate is an order of magnitude smaller on the Nb-doped films despite an enhanced visible light absorption in these materials. The quantum yield is determined to be 0.053, 0.004 and 0.002 for the pure, 10% Nb:TiO2, and 20%Nb:TiO2, respectively. Using an interplay between FTIR and DFT calculations we show that the key surface intermediates are bidentate bridged formate and carbonate, and H-bonded bicarbonate, respectively, whose concentration on the surface can be correlated with their heats of formation and bond strength to coordinatively unsaturated surface Ti and Nb atoms at the surface. The oxidation rate of these intermediates is substantially slower than the initial acetone decomposition rate, and limits the total oxidation rate at t>7 min on TiO2, while no decrease of the rate is observed on the Nb-doped films. The rate of degradation of key surface intermediates is different on pure TiO2 and Nb-doped TiO2, but cannot explain the overall lower total oxidation rate for the Nb-doped films. Instead the inferior photocatalytic activity in Nb-doped TiO2 is attributed to an enhanced electron-hole pair recombination rate due to Nb=O cluster and cation vacancy formation.

    Oxygen Diffusion and Photon-Induced Decomposition of Acetone on Zr- and Nb-Doped TiO2 Nanoparticles2009In: The Journal of Physical Chemistry C, ISSN 1932-7447, E-ISSN 1932-7455, Vol. 113, no 9, p. 3810-3818Article in journal (Refereed)
    Abstract [en]

    We report on the photoinduced decomposition of acetone on Zr- and Nb-doped anatase TiO2 nanoparticles prepared by the sol−gel method in oxygen-free environment (N2) and synthetic air, respectively. Physical properties of the nanoparticles were determined by TEM, SEM, AFM, XRD, and UV−vis spectroscopy. Photoinduced surface reactions were monitored by in situ Fourier transform infrared (FTIR) spectroscopy. Acetone photo-oxidation occurs in the absence of O2 in the reaction gas and is proposed to be due to reactions with photoactivated surface oxygen. In N2 atmosphere a new parallel reaction pathway is found that stimulates surface carbonate formation. A coupled diffusion-reaction model was developed to quantitatively determine the role of O diffusion. The results yield quantitative support to an oxygen surface diffusion mechanism, which depletes the surface from oxygen and gradually deactivates the particles in the absence of external oxygen supply. The diffusion reaction pathway is significant on the doped TiO2 particles. The contribution of this reaction pathway amounts to up to 65% of the total PID rate on Nb- and Zr-doped TiO2 in synthetic air environment, while it gives only a minor contribution on pure TiO2.

    Growth of normally-immiscible materials (NIMs), binary alloys, and metallic fibers by hyperbaric laser chemical vapor deposition2008In: Applied Physics A: Materials Science & Processing, ISSN 0947-8396, E-ISSN 1432-0630, Vol. 91, no 3, p. 507-514Article in journal (Refereed)
    Abstract [en]

    This work demonstrates that two or more elements of negligible solubility (and no known phase diagram) can be co-deposited in fiber form by hyperbaric-pressure laser chemical vapor deposition (HP-LCVD). For the first time, Hg-W alloys were grown as fibers from mixtures of tungsten hexafluoride, mercury vapor, and hydrogen. This new class of materials is termed normally-immiscible materials (NIMs), and includes not only immiscible materials, but also those elemental combinations that have liquid states at exclusive temperatures. This work also demonstrates that a wide variety of other binary and ternary alloys, intermetallics, and mixtures can be grown as fibers, e.g. silicon-tungsten, aluminum-silicon, boron-carbon-silicon, and titanium-carbon-nitride. In addition, pure metallic fibers of aluminum, titanium, and tungsten were deposited, demonstrating that materials of high thermal conductivity can indeed be grown in three-dimensions, provided sufficient vapor pressures are employed. A wide variety of fiber properties and microstructures resulted depending on process conditions; for example, single crystals, fine-grained alloys, and glassy metals could be deposited.

    Use of oxygen-stabilized C60 films for selective chemical vapor deposition1997In: Applied Physics Letters, Vol. 70, no 5, p. 586-588Article in journal (Refereed)
    Abstract [en]

    Thin C60 films exposed to ultraviolet/visible light in the presence of oxygen were used as a selective mask for tungsten chemical vapor deposition on silicon substrates. An uptake of oxygen in the fullerene films as well as a significant increase in their thermal stability resulted from the simultaneous exposure to the radiation and oxygen. The thermal stability and inertness of these films to tungsten hexaflouride, which is readily reduced by silicon to form the metal at 350 °C, allowed selective deposition of tungsten in both ultrahigh vacuum and low pressure environments. X-ray photoelectron spectroscopy and x-ray fluorescence spectroscopy were used to characterize the tungsten deposited on the C60 mask and the unmasked silicon substrate.

    Out-of-plane vibrations of quartz resonators used in quartz crystal microbalance measurements in gas phase2006In: Sensors and Actuators A, Vol. 125, no 2, p. 143-147Article in journal (Refereed)
    Abstract [en]

    The article reveals that shear-mode quartz crystal resonators, currently used in quartz crystal microbalance (QCM) measurements, exhibit an out-of-plane vibration without being in contact with a liquid. Laser assisted CVD was used to deposit carbon-nanoparticles on the surface of a quartz resonator. The in-plane, shear vibration of the quartz resonator, produces a mega-gravity acceleration which induces a sedimentation of the carbon-nanoparticles, while the out-of-plane vibration produces a mega-gravity acceleration, normal to the crystal surface, which induces an expelling of the deposited carbon-nanoparticles. The two opposite effects reveal a complex situation on the quartz resonator surface in QCM measurements.

    The Effect of Biocompatible Coating Layers on Magnetic Properties of Superparamagnetic Iron Oxide Nanoparticles2004In: Hyperfine Interactions, no 156/157, p. 257-263Article in journal (Refereed)
    Abstract [en]

    The effect of the surface coating on the magnetic properties of superparamagnetic iron oxide nanoparticles (SPION) with 8 nm in size has been studied. Four different biocompatible coating layers are considered: poly L,L-lactic acid (PLLA), poly e-caprolactone (PCL), bovine serum albumin (BSA) and gold. The presence of coating layer on the surface of SPION is confirmed by FT-IR spectroscopy. Mössbauer spectroscopy and magnetic susceptibility measurements show that for uncoated SPION and Au@SPION the superparamagnetic fraction is retained. The formation of clusters in the case of BSA@SPION and chain-like structure for PCL@SPION and PLLA@SPION increase the inter-particle interactions resulting in hyperfine magnetic structure observed in the Mössbauer spectra at ambient temperature.

    Improved photon-to-current conversion efficiency with a nanoporous p-type NiO electrode by the use of a sensitizer-acceptor dyad2008In: The Journal of Physical Chemistry C, ISSN 1932-7447, E-ISSN 1932-7455, Vol. 112, no 5, p. 1721-1728Article in journal (Refereed)
    Abstract [en]

    A peryleneimide sensitizer and a covalently linked peryleneimide-naphthalenediimide dyad were prepared and characterized by absorption and emission spectroscopies, electrochemistry, and spectroelectrochemistry. These compounds were chemisorbed on nanoporous nickel oxide electrodes and then studied by femtosecond transient absorption spectroscopy in the presence of a redox active electrolyte (I-3(-)/I-). In both compounds, upon excitation of the peryleneimide unit, an electron is efficiently ejected from the valence band of NiO to the dye with an average time constant of approximately 0.5 ps. In the case of the dyad, the excess electron is shifted further onto the naphtalenediimide unit, creating a new charge separated state. The latter exhibits a substantial retardation of the charge recombination between the hole and the reduced molecule compared with the peryleneimide sensitizer. The photoaction spectra of a sandwich dye-sensitized solar cell (DSSC) composed of NiO films and these new dyes were recorded, and the absorbed-photon to current conversion efficiency (APCE) was three times higher with the dyad than with the peryleneimide dye: 45%. The maximum APCE of approximately 45% is the highest value reported for a DSSC based on a nanostructured metal oxide p-type semiconductor.

    First Example of Low-Valence Ion Substitution in Ln5O(OPri)13: Mixed-Valence Europium Oxoalkoxide [EuIII4EuIIO(OPri)12(HOPri)]*HOPri2005In: Inorganic Chemistry, Vol. 44, no 5, p. 1499-1504Article in journal (Refereed)
    Abstract [en]

    The novel mixed-valence alkoxide [Eu3+4Eu2+O(OPri)12(HOPri)]*HOPri (1) has been prepared and structurally and spectroscopically characterized. The three synthesis routes (i) metathesis of 4EuCl3, EuI2, and 14KOPri combined with hydrolysis with 1H2O, (ii) oxidation of 5[Eu4(OPri)10(HOPri)3]*2HOPri with 1.5O2, and (iii) reduction of Eu5O(OPri)13 with 0.8[Eu4(OPri)10(HOPri)3]*2HOPri all yielded pure 1, whereas (iv) reduction of Eu5O(OPri)13 with 0.36-0.5 mol of europium metal produced impure 1. The compound, having the average Eu oxidation number +2.8, is very sensitive toward further oxidation to Eu5O(OPri)13 and is part of a redox series of europium 2-propoxides with average oxidation states +2.5, +2.8, and +3. The square pyramidal molecular structure, containing an oxo-oxygen atom in the basal plane, is similar to that of the well-known Ln5O(OPri)13; the main difference is the substitution of an Eu3+-OPri pair for an Eu2+-HOPri pair in the basal plane. Fourier transform infrared (FT-IR) and UV-visible spectroscopy showed that the solid-state structure was retained on dissolution in hexane and toluene-HOPri. The compound was further characterized by differential scanning calorimetry and solubility studies.

    Adsorption of Trimethyl Phosphate on Maghemite, Hematite, and Goethite Nanoparticles2011In: Journal of Physical Chemistry A, ISSN 1089-5639, E-ISSN 1520-5215, Vol. 115, no 32, p. 8948-8959Article in journal (Refereed)
    Abstract [en]

    Adsorption of trimethyl phosphate (TMP) on well-characterized hematite, maghemite and goethite nanopartides was studied by in situ DRIFT spectroscopy as a model system for adsorption of organophosphorous (OP) compounds on iron minerals. The iron minerals were characterized by X-ray diffraction (XRD), Raman spectroscopy, transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), specific surface area, and pore size distribution. The minerals were found to consist of stoichimetrically and morphologically well-defined maghemite, hematite, and goethite nanoparticles. Analysis of in situ diffuse reflectance Fourier transform (DRIFT) spectroscopy shows that TMP bonds mainly to Lewis acid Fe sites through the O phosphoryl atom (-P=O-Fe) on hematite and maghemite. On goethite most TMP molecules bond to Bronstedt acid surface OH groups and form hydrogen bonded surface complexes. The vibrational mode analysis and uptake kinetics suggest two main reasons for the observed trend of reactivity toward TMP (hematite > maghemite > goethite): (i) larger number of accessible Lewis acid adsorption sites on hematite; (ii) stronger interaction between the Lewis acid Fe sites and the phosphoryl O atom on TAP for hematite and maghemite compared to goethite with concomitant formation of surface coordinated TMP and dimethyl phosphate intermediates. As a result, on the oxides a surface oxidation pathway dominates during the initial adsorption, which results in the formation of surface methoxy and formate. In contrast, on goethite a slower hydrolysis pathway is identified, which eventually yields phosphoric acid. The observed trends of the reactivity and analysis of the corresponding surface structure and particle morphology suggest an intimate relation between the surface chemistry of exposed crystal facets on the iron minerals. These results are important to understand OP surface chemistry on iron minerals.

    The nucleation of cubic boron nitride (c-BN) on the zigzag edges (100) and (00) of the hexagonal BN (h-BN) prism plane has been theoretically investigated, using a cluster approach and the density functional theory (DFT). Different cubic outgrowths from the edge atoms have been modeled, and the total energies have been set in relation to the total energies for corresponding hexagonal counterparts. The outgrowths were assumed to be derived from the gaseous complexes X2BNH2 and XB(NH2)2 (X=Cl or H), experimentally observed in TACVD and PECVD reactors. It was found that the nucleation of cubic BN is energetically favorable compared to a continuous growth of hexagonal BN on the two edges investigated. The order of relative energy obtained for the various edges considered is; (00)>(100). Moreover, the Cl atoms showed the highest ability to stabilize the cubic nuclei, with one exception. However, the energetic differences between the two terminating species were rather small.

    Atomic layer epitaxy of copper: an ab initio investigation of the CuCl/H2 process I. Adsorption of CuCl on Cu(111)1998In: Applied Surface Science, Vol. 136, p. 137-146Article in journal (Refereed)
    Abstract [en]

    An ab initio investigation of the adsorption and disproportionation of copper(I)chloride on copper(111), two crucial processes in CuCl/H2 copper Atomic Layer Epitaxy is presented. Adsorption of CuCl is energetically most favourable on the two different three-fold adsorption sites with adsorption energies of 152 kJ mol−1. Adsorption on the two-fold bridge site is only 10 kJ mol−1 lower in adsorption energy than on the three-fold sites, whereas adsorption on the on-top site is endothermic by as much as 88 kJ mol−1. As previously noticed in an experimental study, adsorption is not limited by any energy barrier. The disproportionation was investigated for three different arrangements with the composition (CuCl)2. It was confirmed that the formation of (CuCl)2 in the gas phase is favourable, but contrary to earlier experimental findings, no indications of a disproportionation of CuCl could be found. Adsorption of the (CuCl)2 dimers was found to be energetically unfavourable implying that a dissociation to free CuCl molecules is required prior to adsorption.

    Atomic layer epitaxy of copper: an ab initio investigation of the CuCl/H2 process III . Reaction barriers2000In: Applied Surface Science, Vol. 157, no 1-2, p. 92-100Article in journal (Refereed)
    Abstract [en]

    An ab initio investigation of the energy barriers for hydrogen reduction of CuCl on copper(111) surfaces, as well as in the gas phase, has been performed in the present investigation. It is concluded that the elimination of chlorine from CuCl by the addition of H2 proceeds via surface reactions between hydrogen and CuCl both adsorbed on Cu(111). The activation energy for the reaction between CuCl (adsorbed on a threefold site) and H (adsorbed on an adjacent on-top site) is only 53 kJ mol−1, i.e., almost identical to the reaction energy for this surface process. However, the CuCl+H surface reaction should presumably start with both species adsorbed in their preferred threefold sites. By assuming that H diffusion from threefold to top is not hindered by any barrier, the barrier energy for the most possible surface reaction is estimated to become 83 kJ mol−1. This value is in close correspondence to the experimental value of 85 kJ mol−1 that has been previously reported.
