Abstract : The main goal of the research effort described in the report was to achieve substantial improvements in the quality of CdS and related crystals such as CdSe and ZnTe. Two aspects regarding compositional changes in the II-VI compounds are presented: (1) an investigation was made of point-defect equilibria both for complete equilibrium and under ideally quenched conditions, with attention at this time to ZnTe, and (2) the importance of kinetics is emphasized, particularly in regard to the length of time required to attain complete equilibrium in a crystal. A new, promising procedure is also discussed for controlling the composition of the solid in crystal growth by use of an effusion orifice during preparation of the supply.
