CADMIUM TELLURIDE SINGLE CRYSTAL AND PRODUCTION OF CADMIUM TELLURIDE SINGLE CRYSTAL

摘要

PURPOSE:To obtain a large-sized cadmium telluride single crystal, by adding a specific amount of Ge to the molten raw material. CONSTITUTION:In the crystal growth of a CdTe single crystal from a molten raw material, Ge is added to the molten raw material in an amount of 1X1018-9X1021atom/cm3. The molten raw material is pulled up by liquid- encapsulated Czochralski method keeping the temperature gradient near the solid-liquid interface to =100 deg.C/cm along the direction of the crystal growth.
