Composition profiles of Pb0.80Sn0.20Te grown by the normal and inverted Bridgman methods are presented. The growth under stabilized solute gradient decreases the convection, and the final solute distribution corresponds to the partial diffusion-convective mechanism. Also shown are results of high-gravity gradient freeze growth with a destabilizing temperature gradient.
