“…The thermodynamic parameters of stoichiometric crystals can serve as references points for the synthesis of real nonstoichiometric crystals and for their operation. 3, point curve is the experiment for ZnTe [13] At low temperatures, the variance between the experimental results [13] and calculated approximation curve for CP is less than 2 % (Fig. 2).…”

The work is devoted to the theoretical calculations and experimental study of important thermodynamic parameters of II-VI crystals. Cubic sphalerite and hexagonal wurtzite cluster models of polymorphs for stoichiometric II-VI crystals (ZnX, CdX; X  S, Se, Te) have been proposed. In the work one carried out the calculations of thermodynamic parameters under normal conditions and defined the analytical expressions of temperature dependences for energy ΔE, enthalpy ΔH, Gibbs free energy ΔG, entropy ΔS for sphalerite phase stoichiometric crystals of zinc and cadmium chalcogenides. Using the results of DFT-calculations according to equality of Gibbs free energy for sphalerite and wurtzite phases (ΔGS  ΔGW) of zinc chalcogenides crystals we defined phase transition "sphalerite-wurtzite" temperatures, which decreased in the line ZnS (1454 K)-ZnSe (1427 K)-ZnTe (1382 K) and was found the specified region of stability for these polymorphs.

“…Nine species constitute the vapor phase in the Cd-Zn-Te system, Cd(g), Zn(g) and Te k (g), k ¼ 1 to 7. Thermodynamic properties of those, along with CdTe(s), were taken from the Thermodynamic Data Base [12]; for ZnTe(s) thermodynamic functions, recently measured by low-temperature calorimetry [13,14] were used, and ideal solid solution model was assumed for Cd 0.9 Zn 0.1 Te 17d and Cd 0.85 Zn 0.15 Te 17d . Treatment of the experimental results was essentially the same as that developed for Cd 0.95 Zn 0.05 Te 17d and described in detail in our previous publication [10].…”

“…For this purpose, Thermodynamic Data Base IVTAN-TERMO [9] was used as a source of information for crystalline CdTe and all the vapor phase species, Cd(g), Zn(g) and Te k (g), k ¼ 127. In addition, the latest calorimetric measurements of thermodynamic properties of ZnTe(s) [10,11] were utilized, and CdTe and ZnTe activities in the Cd 0.95 Zn 0.05 Te 17d solid solution were calculated assuming an ideal solution model.…”
