Thermodynamic Properties of ZnTe–CdTe Solid Solutions
Source abstract
Abstract
The pseudobinary system ZnTe-CdTe was studied at 899 K by Knudsen cell mass spectrometric measurements. The vapor composition and pressure, ZnTe and CdTe activities, and Gibbs energy of mixing were determined. The results demonstrate that the composition dependences of CdTe and ZnTe activities exhibit, respectively, positive and negative deviations from ideality and that the Gibbs energy of mixing is lower than that of an ideal solution. The p - x section along the pseudobinary join is constructed. At 899 K, a continu- ous series of solid solutions exists in the ZnTe-CdTe system, with no miscibility gap, and sublimation is incon- gruent. The composition dependence of 780-K CdTe activity suggests some evidence of phase segregation.
