The TLZ method which we have invented for growing homogeneous mixed crystals requires diffusion-limited mass transport and convection in a melt should be avoided. In that point, large diameter crystals for substrate use were difficult to be grown on the ground because convection in a melt is intensified by the enlargement of diameter. Therefore, we attempted to grow platy In(1-x)Ga(x)As crystals. Merits of platy crystals are suppression of convection in a melt by limiting the thickness of the melt and achievement of sufficient area for substrate use. Successful scaling up of platy crystals shows that enlargement of the width of platy crystals will not affect the intensity of convection in a melt. This result supports the hypothesis that convection in a platy melt is limited by its small thickness and not by its width., 資料番号: AA0049798002, レポート番号: JAXA-SP-05-036E}, title = {Scaling up of TLZ-grown platy In(0.3)Ga(0.7)As crystals for semiconductor laser substrates}, year = {2006} }
