Abstract
Metal-oxide-semiconductor (MOS) capacitors were formed on 4H-silicon carbide (SiC) using thermally grown silicon dioxide (SiO2) as gate dielectrics, both with and without nitrogen incorporation within the oxide. The field dependence of the charge trapping properties of these structures was analyzed and linked to the observed Fowler-Nordheim current degradation. Furthermore, first considerations were presented that indicate an electron impact emission induced generation of positive oxide trapped charge.
