Abstract Due to superior material properties of SiC for high-voltage devices, SiC Schottky diodes are used in energy-conversion systems such as solar-cell inverters, battery chargers, and power modules for electric cars and unmanned aerial vehicles.

Very fast interface traps have recently been suggested to be the main cause behind poor channel-carrier mobility in SiC metal–oxide–semiconductor field effect transistors. It has been hypothesized that the NI traps are defects located inside the

We investigate the impact of power MOSFET channel width on the power efficiency of a switch-mode power supply. With this analysis, we derive a circuit-specific criterion that minimizes the power dissipated by a power MOSFET, which is based on the rat

Very fast interface traps have recently been suggested to be the main cause behind the rather poor inversion channel mobility in nitrided SiC metal-oxide-semiconductor-field-effect-transistors (MOSFETs). Using capacitance voltage analysis and conduct

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

The performance and reliability of the state-of-the-art power 4H-SiC metal–oxide–semiconductor field-effect transistors (MOSFETs) are affected by electrically active defects at and near the interface between SiC and the gate dielectric. Specifica

This brief presents direct electrical measurement of active defects in the strong-accumulation region of N-type 4H-SiC MOS capacitors, which corresponds to the strong-inversion region of N-channel MOSFETs. The results demonstrate the existence of an

The channel carrier mobility in commercially available 4H-SiC MOSFETs with NO annealed gate oxides is still far below the theoretical limit. It has been suggested that the main reason is high density of very fast interface traps, labeled NI, located
