摘要：

To solve the problem of conductivity-type inversion in wide band gap II-VI compounds the thermodynamical analysis of intrinsic point defects has been performed. The existence of certain critical temperature of heat treatment in equilibrium conditions is shown. Above this temperature it is impossible to obtain the samples with stoichiometry deviation toward non-metals. At the temperatures lower than T-c, the diffusion processes in crystals are retarded and the equilibrium between II-VI crystals and B component vapour cannot be established (B is a component of a binary compound AB). Thus, it is shown that under thermodynamical equilibrium conditions it is impossible to obtain wide hand gap II-VI compounds of p-type conductivity.
