摘要

The valence-band offset (ΔE_v ) has been determined to be ∼2.6 eV at the Ga₂O₃(Gd₂O₃)-GaAs interface, and ∼1.1 eV at the Ga₂O₃(Gd₂O₃)-GaN interface by high-resolution X-ray photoelectron spectroscopy with synchrotron radiation beam. ThePt-Ga₂O₃(Gd₂O₃)-GaAs MOS diode exhibits a current-voltage characteristics dominated by Fowler-Nordheim tunneling. From the current-voltage data at forward and reverse biases, we have extracted a conduction-band offset (ΔE_C) of ∼1.4 eV at the Ga₂O₃(Gd₂O₃)-GaAs interface and an electron effective mass m* ∼ 0.29m_e of the Ga₂O₃(Gd₂O₃) layer. Consequently, the energy-band gap of Ga₂O₃(Gd₂O₃) is ∼5.4 eV, while ΔE_c for the Ga₂O₃(Gd₂O₃)-GaN interface is ∼0.9 eV.
