SiC and GaN – The Potential of Wide Bandgap Semiconductors

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 source … The different polytypes have widely ranging physical properties. 3C-SiC has the highest electron mobility and saturation velocity because of reduced phonon scattering resulting from the higher symmetry. The band gaps differ widely among the polytypes ranging from 2.3 eV for 3C-SiC to 3 eV in 6H SiC to 3.3 eV for 2H-SiC. In general, the greater the wurtzite component, the larger the band gap. Among the SiC polytypes, 6H is most easily prepared and best studied, while the 3C and 4H … ctsgw_proxyd
