Thermodynamic properties of the solid solutions ZnTeCdTe, ZnTeHgTe and CdTeHgTe

Abstract The Gibbs free energy, enthalpy and entropy of formation of the ZnTeCdTe, ZnTeHgTe and CdTeHgTe solid solutions were determined by measuring the e.m.f. of high temperature galvanic cells. All solid solutions investigated exhibit positive deviations from Raoult's law. Thermodynamic stability of all solid solutions decreases with decreasing temperature and the energetics of formation depends on the interaction of components of the metallic sublattice.
