Webconductivity or deep levels for achieving semi-insulating (SI) SiC. Impurities, especially transition metals generate defect levels deep in the band gap of SiC, which trap charge carriers and thus reduce the charge carrier lifetime. Transition metals, such as vana-dium, are used in SiC to compensate the residual nitrogen doping. WebMay 31, 2024 · Near-interface traps are more critical compared to bulk traps for the mobility of SiC MOSFETs. The oxidation process can also cause the injection of carbon into SiC substrate. This injected carbon can exist in different forms such as carbon interstitials ( C i ) and carbon di-interstitials ( C i ) 2 to further degrade the FET channel mobility [ 4 – 6 , 24 ]. imlay city bowling alley
