Spectral and Kinetic Characteristics of the Luminescence of Ga2O3 Crystals Excited by Nano- and Subnanosecond Electron Beams

Abstract

Abstract: The spectral and kinetic characteristics of the emission of Sn- and Fe-doped Ga₂O₃ crystals excited by a nanosecond electron beam are studied. A new cathodoluminescence band of the Fe-doped crystal is revealed with a maximum at λ_m = 315 nm. Comparison with the data obtained with a subnanosecond duration of the beam current pulse is performed. It is shown that, with increasing duration of the beam current pulse, the main contribution is made by cathodoluminescence in the range of 300–450 nm.
