GROWTH OF SINGLE CRYSTAL CADMIUM-INDIUM-TELLURIDE

摘要

A method for producing a large high-quality single crystal of Cadmium-Indium-Telluride is disclosed wherein a stoichiometric crystal is produced from a non-stoichiometric melt composition. An initial melt composition corresponding to approximately 62 mole % to 90 mole % In2Te3 and 38 mole % to 10 mole % CdTe, respectively, is prepared and sealed in an evacuated ampoule and then heated to completely melt the mixture. Growth of a single crystal of CdIn2Te4 is initiated and maintained from the non-stoichiometric melt mixture by lowering the melt through its corresponding phase-equilibrium melting point. Upon cooling to room temperature, the large single crystal so produced is removed from the ampoule.
