Research progress of irradiation damage for GaAs materials and devices
Abstract:As a kind of III-V semiconductor materials, GaAs, with direct band gap and high carrier mobility, has a good anti-radiation ability, makes that an important candidate for the preparation of space devices. However, when the semiconductor devices were working in space, they will be affected by the radiation of the complex space particles, resulting in the degradation of the device performance, the decrease of the reliability and the limitation of the lifetime. Therefore, it is of great significance to anaysis the irradiation effect damage of the GaAs material. This paper reviews the research progress on the damage effect of different particle materials on GaAs materials and devices, expounds the influence of different particle irradiation sources on the structure and luminescent properties of GaAs. This paper has practical significance for the further application of GaAs materials in space environment.
