Method for making semiconductor crystals

摘要

A planar solid-state recrystallization process for growing mercury cadmium telluride (MCT) crystals suitable for semiconductor applications, in which molten MCT material is solidified in a horizontal sealed ampoule having a substantial portion of its lower external surface (i.e. a part of the ampoule surface which contains molten material) in heat-transfer contact with a heat sink, and having no substantial portion of the vapor-containing segment of the external ampoule wall in contact with that heat sink.
