Growth of semiconductor compound single crystal InSb by floating zone method (M-3)

Floating zone methods have potential applications in growing single high-quality semi-conductor crystals. In this method, melts can be sustained without containers and, therefore, are free from contamination from the containers. The main objective of this project is to use the Image Furnace to study a large diameter, (20 mm) single crystal of InSb under microgravity conditions. The behavior of the liquid column is recorded on the VTR tapes and is compared with what is expected theoretically. The single crystal grown in space is characterized by comparing it with single crystals grown on the ground with respect to crystallographic and electronic properties. The goal of this project is to confirm the effects of the microgravity on the single crystals.
