Abstract Characterization of near-interface traps (NITs) in commercial SiC metal–oxide–semiconductor field-effect transistors (MOSFETs) is essential because they adversely impact both performance and reliability by reducing the channel carrier mo

Oxide traps existing in 4H-SiC MOS capacitors with fast response times that are active in the strong accumulation and depletion regions were characterized by an integrated-charge method. The method is based on the measurement of charging and discharg

Two different equations for the current through voltage-dependent capacitances are used in the literature. One equation is obtained from the time derivative of charge that is considered as capacitance-voltage product: dQ/dt = d[C(V )V ]/dt = C(V)[dV
