1 Introduction β-Ga2O3 is a semiconductor with ultra-wide bandgap in the deep UV range of ≈5 eV.[1] Ga2O3 can crystalize in four distinct phases, among them the β is the most thermodynamically stable up to its melting point of ≈1800 °C.[2, 3] The superb material properties of β-Ga2O3 enable its technological applications in UV-optoelectronic devices and high-temperature high-power sensors and photodetectors.[4-8] Moreover, due to its relatively low-phonon energies, Ga2O3-based low-energy...
