Abstract [en]

The possibility of engineering multilayered nanostructures and coatings with a wide variety of compositions has in the last decades attracted a great deal of scientific interest. In fact, multilayered structures with tailored properties have been investigated for solar conversion [1], the semiconductor industry [2] and tribological systems [3].Electrochemical engineering has emerged as a particularly promising technique for fabrication of nanostructured electrodes with excellent control on morphology [4]. The technique shows great promise in the copper system as Cu/Cu2O multilayers have been produced by allowing spontaneous potential oscillations to dictate the deposition [5, 6].Although this natural phenomenon provides a simple route to obtain mixedcomposition, improved control is required to obtain fine detailed multilayers. The presented study has been focused on preventing spontaneous potential oscillations to provide controlled deposition of Cu/Cu2O multilayers. In addition copper based multilayers have hereby been transported into the world of 3D electrodes via a one-step electrodeposition fabrication.
