Characterisation of cadmium telluride bulk crystals grown by a novel "multi-tube" vapour growth technique

The structural properties of a boule of bulk cadmium telluride grown at the relatively low temperature of 700 degrees C by a novel "multi-tube" vapour growth technique have been profiled in the growth direction by triple axis X-ray diffraction, defect revealing etching and photoluminescence. Conside rable improvement in quality, as evidenced by a reduction in etch pit densi ty and photoluminescence and X-ray linewidths, is observed through the boul e. (C) 1999 Elsevier Science B.V.
