The effects of a traveling magnetic field (TMF) on vertical gradient freeze (VGF) growth of cadmium zinc telluride
(CZT) are studied using a coupled model of magnetic induction, fluid dynamics, and heat transfer. Simulations
are performed to determine the influences of current and frequency on melt flow and growth interface shape. A
downward traveling electromagnetic wave drives flow downward at the wall, which tends to flatten the interface,
whereas an upward traveling wave has the opposite effect. TMF makes a significant impact on interface shape
in the absence of thermal buoyancy, but is ineffectual under realistic conditions in a 4 inch diameter ampoule,
for which buoyancy dominates Lorentz force throughout the melt.
