Sic trap
WebIt is shown that the vacancies and the oxygen interstitial can be excluded as the origin of such NIT, while the silicon interstitial and carbon dimers give rise to gap levels in the energy range inferred from experiments. The properties of these defects are discussed in light of the knowledge about the $\mathrm{SiC}∕{\mathrm{SiO}}_{2}$ interface. WebDec 1, 2024 · As mentioned above, SiO2 growth is applicable to SiC substrates. However, the resultant SiC/SiO2 interface contains many defects, trap states, and dangling bonds not found in the traditional Si/SiO2 interface, due to the fact that SiO2 grown on 4H, 6H, and 3C SiC polytypes has sufficient lattice mismatch to manifest in excessive interfacial ...
