WebOne of the most important areas of investigation has been the study of point defects. Defects in the oxide lead to shifts in threshold voltage in MOSFET’s [1]. Also, the residual unpassivated defects at the Si/SiO 2 interface are responsible for decreased surface mobility, and for “soft” threshold characteristics. WebApr 10, 2024 · Achieving low conduction loss and good channel mobility is crucial for SiC MOSFETs. However, basic planar SiC MOSFETs provide challenges due to their high density of interface traps and significant gate-to-drain capacitance. In order to enhance the reverse recovery property of the device, a Schottky barrier diode (SBD) was added to the … WebOct 1, 2013 · An original method to accurately evaluate the MOS interface state density has been proposed.
