论文摘要
通过（010）（alxga1-X）2O3/GA2O3异质结构中观察到的Shubnikov de Haas振荡的磁通测量和分析，已经研究了（010）GA2O3 GA2O3二维电子气体（2DEG）中Landau水平的自旋分解。分析表明，旋转分解是由Zeeman效应引起的。通过将振荡的第一和第二个谐波拟合为磁场的函数，我们确定Zeeman拆分的大小为0.4 $ \hbarΩ_c$，对于垂直于2DEG的磁场，磁场的相应有效G-FACTOR为2.7。
Through magneto-transport measurements and analysis of the observed Shubnikov de Haas oscillations in (010) (AlxGa1-x)2O3/Ga2O3 heterostructures, spin-splitting of the Landau levels in the (010) Ga2O3 two-dimensional electron gas (2DEG) has been studied. Analysis indicates that the spin-splitting results from the Zeeman effect. By fitting the both the first and second harmonic of the oscillations as a function of magnetic field, we determine the magnitude of the Zeeman splitting to be 0.4$\hbarω_c$, with a corresponding effective g-factor of 2.7, for magnetic field perpendicular to the 2DEG.
