BULK VAPOR GROWTH OF CDTE

Growth of CdTe crystals was performed reproducibly in 130 Torr hydroge n atmosphere by a method of self nucleation and growth with no contact between crystal and ampoule wall [K. Grasza et al., J. Crystal Growth 123 (1992) 519]. The growth temperature was 960 degrees C and the fur nace translation rate 4 mm/day. Large CdTe single crystals up to 15 cm (3) have been grown using this method. The way to increase the size of crystals and results of growth of crystals up to 3.5 cm in length and 5.5 cm diameter are presented.
