Improvements in the purification of cadmium telluride by

Nov 01, 1970· Journal of Crystal Growth 7 (1970) 329332 North-Holland Publishing Co. Several improvements have been made in the vertical zone re- fining technique used for the purification of cadmium telluride. The graphite susceptor used in RF heating is a split ring instead of the full ring used previously. Therefore, the molten zone is 1.

Impurity reduction technique for mercury cadmium telluride

Abstract. The disclosure relates to a method for reducing impurity concentration in mercury cadmium telluride alloys wherein impurities are attracted to a region saturated with second phase tellurium during annealing in a saturated mercury atmosphere where the second phase tellurium and the impurities attracted thereto can be removed by polishing, etching, grinding, or the like.

Preparation and photoluminescence characterization of high

Extremely high-purity CdTe single crystals have been obtained by the traditional vertical Bridgman technique, beginning with the refining of tellurium material by the normal freezing method. The purification effect of normal freezing on tellurium has been confirmed to be very effective. This effect was also used to prepare extremely high-purity CdTe single crystals.
