Application of a rotating heat field in Bridgman-Stockbarger crystal growth

This note reports the use of heat field rotation as a contact-free influence upon the heat-mass transfer processes in vertical Bridgman-Stockbarger crystal growth. The modified heating furnace which allows the creation of a rotating heat field with various amplitude-frequency characteristics is described. A high-quality, conical, single crystal of AgGaS2 of 30 mm diameter and 80 mm length was grown using this heat field rotation method (HFRM). (C) 2004 Elsevier B. V. All rights reserved.
