However, direct control of the transport rate is impossible and this uncontrollability makes compositionally homogeneous crystal growth extremely difficult. Objectives of this research are to invent a new method for growing compositionally homogeneous alloy crystals that can control the mass transport rate at the growth interface directly and can avoid the effects of residual acceleration and g-jitter on the crystal growth from a melt and to apply the new method to the growth of alloy crystals such as In(0.3)Ga(0.7)As and to verify the feasibility of the new method. In(0.3)Ga(0.7)As is promising as a substrate for laser diodes for 1.3 micrometer wavelength but its large homogeneous single crystals have never been obtained on the ground.
