Abstract
The thermodynamic and photochemical stability of Ga2O3–GaAs interfaces fabricated using in situ multiple-chamber molecular beam epitaxy has been investigated. The Ga2O3 films were deposited on clean, atomically ordered (100) GaAs surfaces using a molecular beam of gallium oxide. Thermally induced degradation of electronic interface properties such as interface recombination velocity S (5750±1250 cm/s) and interface state density Dit(mid-1010 cm−2 eV−1 range) has not been observed after rapid thermal annealing at 800 °C. Furthermore, no interface degradation has been detected during exposure to high intensity laser light. The preservation of excellent electronic interface properties and the absence of interfacial chemical reactions are attributed to AsxOy and elemental As free Ga2O3–GaAs interfaces.
