The strong bonding in wide bandgap semiconductors gives them an intrinsic radiation hardness. Their suitability for space missions or military applications, where issues of radiation tolerance are critical, is widely known. Especially b-Ga2O3, an ultra-wide bandgap material, is attracting interest for power electronics and solar-blind ultraviolet detection. Beside its superior thermal and chemical stabilities, the eï¬ects of radiation damage on Ga2O3 are of fundamental interest in space-based and some terrestrial applications. We review the eï¬ect on the material properties and device characteristics of proton, electron, X-ray, gamma ray and neutron irradiation of b-Ga2O3 electronic and optoelectronic devices under conditions relevant to low earth orbit of satellites containing these types of devices.
