Global Simulation of CdZnTe Crystal Growth by Detached Solidification Method

Detached solidification represents perhaps the most exciting recent development for the growth of bulk, single-crystal materials from the molten phase. This method combines appealing characteristics of both the classical Bridgman and Czochralski methods, which can improve the crystal quality dramatically. In this paper, the global simulations of CdZnTe detached solidification are conducted with gap widths of 0, 0.5 and 1 mm. The temperature distribution, the stream function distribution and the shape of the melt/crystal interface are displayed and analyzed in microgravity and on earth.
