Description
  • Gallium Arsenide (GaAs) is an important and mature group III-Ⅴ compound semiconductor, it’s widely used in the field of optoelectronics and microelectronics. GaAs is mainly divided into two categories: semi-insulating GaAs and N-type GaAs. The semi-insulating GaAs is mainly used to make integrated circuits with MESFET, HEMT and HBT structures, which are used in radar, microwave and millimeter wave communications, ultra-high-speed computers and optical fiber communications. The  N-type GaAs is mainly used in LD, LED, near infrared lasers, quantum well high-power lasers and high-efficiency solar cells. Properties:
