Reanalysis of Solidus Points and Te Chemical Potential for Te-rich CdTe(s)
Journal of Phase Equilibria and Diffusion
The author’s previously published partial pressures of tellurium over tellurium-rich CdTe are reanalyzed to yield new solidus points as well as temperatures and partial pressures for compositions within the homogeneity range. Although the results are qualitatively the same as before, they are more satisfactory in that some thermodynamic inconsistencies have been removed. The composition range of the CdTe phase extends slightly beyond the equal atom fraction,X Te=0.5, to a Te-rich composition of (X Te−0.5)=(1 to 7)×10−5. The data are in fair agreement with that obtained from total pressure measurements at generally higher compositions. Since both types of measurement are near the limits of attainable accuracy, their agreement would seem to confirm the essential correctness of both.
