A high density of fast band-edge traps exists in SiC MOS devices, which are active in the sub-threshold region 6. For gate voltages higher than the threshold voltage V T, the Fermi level is in the conduction band due to the quantum-confinement effect 7, 8. Therefore, the electrons on interface and near-interface traps with energy levels aligned ...

Among SiC MOSFET structures, the trench MOSFET has a low channel resistance thanks to its high channel density and mobility[5, 6]. However, in a high-voltage SiC MOSFET (a voltage of 3.3 kV or above), the channel resistance does not have a significant effect because of the high drift resistance. In addition, at high voltages, the trench MOSFET ...
