Heat transfer is perhaps the most important element in the design and operation of melt crystal growth processes. This chapter presents a primer on heat transfer fundamentals, followed by a more focused discussion of specific heat transfer interactions during melt crystal growth. To provide motivation and context for this discussion, the classical Bridgman crystal growth method is reviewed via historical perspectives of practice and theory. Finally, a research vignette is presented on developments to control the shape of the solid-liquid interface via heat transfer engineering during the Bridgman growth of cadmium zinc telluride. It is argued that the future development of melt crystal growth will rely on fundamental advances in the understanding of growth mechanisms coupled with skillful application of powerful computational models for process analysis and design.
