INFLUENCE OF EXTERNAL MAGNETIC FIELD ON THE FLOWFIELD OF MOLTEN SEMICONDUCTORS DURING CZO-CHRALSKI CRYSTAL GROWTH PROCESS -ANUMERICAL SIMULATION

. Numerical results show that the external magnetic field influences significantly the flow field of molten semiconductors during Czochralski crystal growth process. The melt flow could be heavily damped by a magnetic field with intensity of several thousand gauss, while the temperature field is nearly unaffected because of very low Prandtl number.
