AB  - A pseudo steady‐state model is developed to study heat transfer, fluid
flow, and the interface shape in the liquid encapsulated vertical Bridgman
crystal growth. The model, which is governed by momentum, heat, and overall
mass balances in the system, is solved by a finite‐volume/Newton method. Flow
and temperature fields, as well as unknown melt/crystal and melt/encapsulant
interfaces, are calculated simultaneously. Sample calculations are mainly
conducted for the GaAs/B2O3/PBN system. Calculated
results for the Germanium/graphite system are compared with finite element
calculations by Adornato and Brown, and they are in good agreement. The
effects of some process parameters, including the growth speed, ambient
temperature profile and heat transfer conditions, on flow patterns,
temperature fields and the interface shape are illustrated through calculated
results. Interface inversion from concave to convex, by modifying the ambient
temperature profile, is also demonstrated through computer simulation.
Particularly, through an inverse problem approach, a flat interface can be
easily obtained for various operation conditions.
