POLYASSOCIATIVE MODEL OF A2B6 SEMICONDUCTOR MELT AND p-T-x PHASE EQUILIBRIA IN Zn-Cd-Te SYSTEM

Abstract

This work presents a numerical analysis of p-T-x phase equilibrium in the Zn-Cd-Te ternary system in the framework of the polyassociative solution model. On the basis of the experimental data on p-T-x phase equilibrium in the ternary system, thermodynamic functions describing the formation of liquid associates were found. It was shown that the results of the mixing of components in the Zn-Cd-Te ternary melt are related to the occurrence of ZnCdTe and ZnCdTe3 associates. Dissociation parameters of these complexes were calculated and subsequently used in order to efficiently describe p-T-x phase equilibrium of the system in a wide temperature range.

Keywords:

phase equilibria, solubility, liquid phase epitaxy, semiconducting II-VI materials
