Abstract
We present EXAFS measurements on a few semiconducting, zincblende II–VI alloys. The measurements reveal the real microscopic structure of these materials which is different from that of the pure constituents. Although the lattice constant of these alloys change considerably with composition, the near-neighbour anion-cation bond lengths stay almost undisturbed in comparison with those of the pure materials, while the next-near-neighbour distances show complicated multi-modal distribution. These experimental facts led to the formulation of the structural model for such alloys and allowed to estimate the elastic energy of the distorted crystal lattice. This, in turn, was used to describe the thermodynamic functions of mixing. In particular, we derive the interaction parameter and the critical temperature in the framework of the quasi-chemical approximation and address the problem of the correlations in the chemical disordered sublattice.
