Design of a Travelling Magnetic Field for Vertical Gradient Freeze - Crystal Growth

Lantzsch, R.; Galindo, V.; Gerbeth, G.; Cröll, A.

The melt flow in the vertical Gradient Freeze growth of GaAs can efficiently be controlled by an external travelling magnetic field. The latter directly provides for a poloidal flow in the molten part. Controlling this flow offers the possibility to influence the interface shape, to increase the growth rate or to improve the homogeneity of the crystal. We report on the design of the magnetic field system and preliminary flow measurements with it.
