Abstract

In situ characterization of β-Ga 2 O 3 flakes during proton irradiation is performed using ionoluminescence and electrical measurements. The quenching of the native blue-UV emission bands due to irradiation-induced defects in real time is monitored by ionoluminescence. Measurements of the I–V characteristics during irradiation present a good response of Ga 2 O 3 for particle detection and a good radiation resistance.
