We present numerical simulations of the high temperature solution growth (HTSG) of silicon carbide (SiC) crystals. From a global simulation model, we investigate the influence of rotating magnetic fields (RMFs) and traveling magnetic fields (TMFs) on the crystal growth rate. The results reveal that heat and mass transfers are affected by magnetic fields. We show that direction of the solute flux must be controlled to increase the growth rate. For example, in presence of TMFs directed downwards the growth rate increases up to three times compared with the pure thermal HTSG. The proposed HTSG system coupled with magnetic fields has the same growth rate possibility as in the sublimation technique. (C) 2011 Elsevier B.V. All rights reserved.
