Abstract : It was found that vertical crystal pulling of ZnSe and CdS is possible only in pressurizedATMOSPHERES OF UNSATURATED VAPORS, SINCE SATURATED VAPORS ARE TOO OPAQUE TO PERMIT VISIBILITY. Several new systems for crystal growth under pressure are described, and a new feedback circuit for control of the RF generator has been invented. The properties of melt-grown ZnSe have been investigated, and an extensive survey of contacts to ZnSe was initiated. ZnSe and CdS form solid solutions, whereas CdS and ZnTe are immiscible. Materials which hold promise for the preparation of alloyed contacts have been found. Several single and multiple films with interesting properties have been obtained by evaporation, and an analysis of SCL hole currents in ZnSe has been carried out. It has been found that a glass consisting of As-S-Br is transparent from .5 to 13 microns GaP crystals have been prepared by vapor phase reaction starting from GaN. (Author)
