Abstract
Fabrication of single crystals of III-V semiconductor materials such as, e.g., indium phosphide by pulling from a melt may be hampered by twin formation. It has been discovered that twin formation is prevented by adjusting processing parameters such as, e.g., melt temperature, rotation rate, thermal gradients, and pull rate so as to limit rate of diameter enlargement of a boule. Specifically, diameter enlargement preferably does not exceed 0.3577 times the increase in length of a boule being pulled.
