In the Space Shuttle or in the International Space Station (ISS), residual acceleration on the order of 10(exp -3) - 10(exp -4)g still remains and it causes inhomogeneous distribution of the solute, but this method compensates solute loss at the growing interface due to the residual acceleration and produces homogeneous crystals. On the ground-based experiments, single crystals of In(x)Ga(1-x)As with x = 0.20 - 0.33 having longer than 20 mm homogeneous parts were obtained by this method., 資料番号: AA0029300001, レポート番号: NASDA-TMR-000007E}, title = {Homogeneous In(0.3)Ga(0.7)As crystal growth by the graded solute concentration method}, year = {2000} }
