- Аннотация: Isovalent ternary solid solutions of A(IV)B(VI) materials such as Pb1-y(S(x)Se1-x)y, Pb1-y(S(x)Te1-x)y and Pb1-y(Se(x)Te1-x)y can been used as lattice-matched heterostructures for IR lasers and detectors. The solid/vapour equilibrium has been studied by the method of rapid quenching of crystals of solid solutions prepared by three-zone furnace annealing at fixed T, P(Pb) and P(Pbx). Hall-coefficient and lattice-constant measurements on quenched samples were analysed as functions of T and P(Pb). The curves of n, p as functions of T and P(Pb) were used to determine the degree of ionization of defects and to calculate the constants of Frenkel disordering in the form: K = K0 exp(-DELTA-H/k(B)T).
