Abstract

Thermocapillary flow dominates melt convection in floating zone crystal growth under microgravity, and a steady and axisymmetrical thermocapillary flow is helpful for the high quality crystal growth, however thermocap-illary flow tends to become non-axisymmetrical and unsteady with increasing grown crystal size. To investigate the convection control by rotating magnetic field (RMF) in semiconductor crystal growth, thermocapillary flow in a three dimensional floating half zone model is simulated. The result indicates the three-dimensional unstable thermocapillary flow returns to a steady and axisymmetric convection in a proper RMF under microgravity.
