Abstract
The spin splitting study of the two-dimensional electron gas (2DEG) for analyzing the enhancement and anisotropy of the Landau g factor in modulation-doped AlGaN/GaN heterostructures was presented. The study measured the magnetotransport properties at low temperatures and high magnetic fields. At magnetic field higher than 5.4 T and a temperature of 1.4 K, the spin splitting was observed in Shubnikov-de Hass oscillations. The ratio of the transverse effective and longitudinal effective g factor indicated large differences between the transverse and longitudinal g factors. The polarization-induced electric field at the heterointerface was found to be the cause behind the anisotropy of the Landau g factor.
