Abstract This study examines the effect of crucible conductivity in minimizing convection and solute segregation in a Bridgman crystal growth system. Crystal diameter to length ratios from 0.5 to 2.5 are considered. A quasi-steady state numerical method is used to model the directional solidification of gallium doped germanium. The coupled governing equations for the melt, solidified crystal, and the ampoule wall are solved subject to appropriate boundary and interface conditions to determine the velocity, temperature, and concentration distributions. Results are presented at reduced gravity and include the effects of reducing the dimensionless ampoule conductivity from 0.67 to 0.05.
