The melt-growth and characterization of cadmium telluride

Abstract
Developments in the melt-growth of CdTe are reviewed particularly with respect to techniques for controlling the dissociation pressure. The potential merits of Pressure Balancing are considered together with the results of a preliminary LEC growth investigation. The charac- terization of the LEC crystals involves a survey of the main defects-low angle grain boundaries twins, dislocations, precipitates, impurities and impurity defects-together with a discussion on their origin, and experience and suggestions for their elimination or control.
