RANDOM MICROSCOPIC MODEL OF QUATERNARY ALLOYS

A random model of microscopic structure of zinc-blende type A(1-x)B(x) C(1-y)D(y) quaternary alloys, based entirely on the elastic bond-stret ching and bond-bending forces of two-element components AC, AD, BC, an d ED, was constructed. The model was applied to Cd1-xMnxTe1-ySey quate rnary alloys and the calculated nearest-neighbor distances were compar ed with the experimental data. Additionally, a possibility of particle exchange (within each sublattice) was included into the model and a p ossibility of studying the preferential coordination was discussed.
