Abstract
The horizontal Bridgman growth of cadmium zinc telluride is investigated with respect to the coupling of heat, momentum, and mass transport using a two-dimensional, time-dependent, finite element model. Growth at crucible translation rates fast enough to result in purely transient behavior is shown to encourage the favored shelf growth morphology and reduce the axial segregation of zinc in the shelf. Fast crucible translation violates the conventional goal of quasi-steady melt growth conditions; however, this time-dependent processing strategy yields beneficial results for the growth of this material.
