Abstract : The short-range order of II-VI substitutional solid solutions is investigated experimentally using the EXAFS technique. The distortion energies of the five tetrahedra which form the basic lattice framework of these solutions are evaluated by a simple Valence-Force-Field VFF model. Within the modified III order Quasi Chemical Approximation, we compute the free energy of mixing, the probability distribution and the coherent phase diagrams of several II-VI and III-V pseudobinary alloys.
