Abstract : Preparation, purification, crystal growth, and measurement of the fundamental bulk properties of CdS, CdSe, ZnTe, and CdS-CdSe mixed crys als are summarized. Large single crystals of CdS, CdSe, and ZnTe were prepared by the ReynoldsGreene sublimation method. CdSe crystals were also prepared by gradient freezing. Methods for preparing test specimens for electrical and optical measurements are presented. Procedures for conducting high-temperature equilibrium studies on CdSe are discusse . Extensive Hall-effect and conductivity measurements between 77 and 500 K were made on miscellaneous crystals. Other measurements included melting points, refractive indexes, elastic, dielectric, piezoelectric and lattice constants. Correlations were obtained between the sign of the polar axis in CdSe and ZnTe and the X-ray determined AB l yer order. (Author)
