Title: Production Crystal Growth System Design for Aluminum Antimonide (AlSb)
Agency: DOE
Contract: DE-FG02-05ER84140
Award Amount: $95,035.00
 

Abstract:

79504S05 The growth of large semi-insulating single crystals of aluminum antimonide (AlSb) for the potential application of room temperature, high-energy, gamma-ray radiation detection, needed for radiation detection, is hindered by the presence of melt slag during Czochralski crystal growth. This project will design a production crystal grower for the Al ¿ Sb system that allows growth of an semi-insulating AlSb crystal ingot without the presence of melt slag. In Phase I, a set of engineering drawings will be developed and produced for the aluminum antimonide production crystal growth system. Phase II will construct and operate a crystal growth system for the production of large (three-inch diameter) semi-insulating crystals of AlSb. Commercial Applications and Other Benefits as described by the awardee: In addition to the application for radiation detection, a crystal growth system for the manufacture of large semi-insulating aluminum antimonide single crystals should have application to low-noise, low-power, high-speed electronic antimonide/arsenide heterostructure devices.
