Abstract [en]

By means of ab initio pseudopotential calculations, we investigate the effect of lattice mismatch on the intrinsic properties in the dilute ZnOxSe1- x alloys. The substitution of isovalent elements having a large electronegativity and size mismatch with respect to the replaced atoms leads to strong nonlinear effects in the properties of the host crystal. From a detailed analysis of the bowing, we notice that the relative contribution of the three components ( volume, charge exchange, and strain) shows that the most significant effect is caused by the structural relaxation.
