Computational modeling has provided the understanding needed to unravel many of the unusual characteristics of the melt growth of cadmium zinc telluride. Results are presented that clarify the origin and benefit of horizontal Bridgman shelf growth employed for infrared substrate material. Another example provides insight on how a non-classical approach may provide improved outcomes using multiple-zone, gradient-freeze furnaces for the vertical Bridgman growth of bulk material for gamma radiation detectors.
