METHOD FOR GROWING SINGLE CRYSTAL OF ZN-GROUP VI ELEMENT COMPOUND

摘要

PURPOSE:To convert polycrystals of Zn-group VI element compound such as ZnSe into single crystal with high reproducibility. CONSTITUTION:The polycrystals 1 deposited from Zn-group VI element compound vapor are heat-treated, as they are stressed with more than 7kg/cm<2> totaling the inner stress and the outer stress by the clamping device 3 in the vapor atmosphere of the same element in group VI to give single crystal of the Zn-Vl element compound.
