Single crystal platelets of Cadmium Sulfide were grown by evaporation of pure Cadmium Sulfide powder in a gas stream and subsequent crystallization by gradual cooling of the vapor phase. Parameters which influence the rate of growth were defined and varied in order to optimize the growth process. Two variables, the concentration of Hydrogen Sulfide in the carrier gas and the temperature gradient in the crystallization region, were selected for further investigation. A theoretical model has been developed which makes it possible to calculate the supersaturation in the gas phase for the different growth conditions and which relates this supersaturation with the habit of the crystals. The results of the model are compared with the experimental results. Author
