A Model of Dopant Transport During Bridgman Crystal Growth With Magnetically Damped Buoyant Convection

摘要

This paper presents a model for the unsteady transport of a dopant during the vertical Bridgman crystal growth process with a planar crystal-melt interface and with an exter- Nally applied axial magnetic field. This dilute mass transport depends on the convective and diffusive mass transport of the dopant. The convective mass transport is driven by Buoyant convection in the melt, which produces nonuniformities in the concentration in both the melt and the crystal.
