Through magnetotransport 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 both the first and second harmonics of the oscillations as a function of magnetic field, we determine the magnitude of the Zeeman splitting to be 0.4 ħωc, with a corresponding effective g-factor of 2.7, for the magnetic field perpendicular to the 2DEG.Through magnetotransport 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.

(010) β-Ga2O3 二维电子气中的塞曼自旋分裂

通过磁输运测量和对 (010) (AlxGa1-x)2O3/Ga2O3 异质结构中观察到的 Shubnikov de-Haas 振荡的分析，(010) Ga2O3 二维电子气 (2DEG) 中朗道能级的自旋分裂已经学习了。分析表明自旋分裂是塞曼效应的结果。通过拟合作为磁场函数的振荡的一次和二次谐波，我们确定塞曼分裂的幅度为 0.4 ħωc，对应的有效 g 因子为 2.7，对于垂直于 2DEG 的磁场。通过磁输运测量和对 (010) (AlxGa1-x)2O3/Ga2O3 异质结构中观察到的 Shubnikov de-Haas 振荡的分析，(010) Ga2O3 二维电子气 (2DEG) 中朗道能级的自旋分裂已经学习了。分析表明自旋分裂是塞曼效应的结果。通过拟合作为磁场函数的振荡的一次和二次谐波，我们确定塞曼分裂的幅度为 0.4 ħωc，对应的有效 g 因子为 2.7，对于垂直于 2DEG 的磁场。
