Book excerpt: Gallium arsenide crystals were grown 1 cm in diameter by the gradient freeze technique and by the travelling heater method (THM) using a gallium zone. Optimal conditions for THM with a 1 cm long resistance heater were determined to be a heater temperature of 900C, a lowering rate of 1.5 mm/day, a 6 to 10 mm long zone, a 1 cm long seed and a feed ingot over 2 mm long. Experimental results agreed well with a classical constitutional supercooling analysis. Preliminary experiments of THM growth of Ga(x)In(1-x)Sb and Ga(x)Al(1-x)As were also performed. Classical constitutional supercooling theory was extended to multicomponent systems. (Author).
