Popis: The SiC vacuum field-effect transistor (VacFET) was first reported in 2010 as a diagnostic tool for characterizing the fundamental properties of the inverted SiC semiconductor surface without confounding issues associated with thermal oxidation. In this paper, interface state densities are extracted from measurements of threshold voltage instability on a SiC VacFET and a SiC MOSFET. It is shown that removing the oxide can reduce the interface state density by more than 70%.
