Introducing the space growth of GaAs single crystals

Abstract

Three types of GaAs single crystals, i.e. Te-doped, Si-doped as well as semi-insulating GaAs (SI-GaAs) single crystals, have been grown in Chinese recoverable satellites. This paper reports the results of property investigations, including electrical, optical, opto-electrical properties and structural characteristics. The space-grown SI-GaAs single crystal is used for fabricating low noise FET devices, and interesting results are obtained.
