Dynamical Analysis of Melt Flow in the Bridgman Process
WebMay 14, 2006 · During the vertical Bridgman process, a single semiconductor crystal is grown by the solidification of an initially molten semiconductor contained in an ampoule. The motion of the electrically conducting molten semiconductor can be controlled with an externally applied magnetic field.
