Abstract
Small bursts of inversion layer charge in 4H-SiC metal oxide semiconductor capacitors leak through the oxide layer leading to discontinuities during capacitance-time measurements. This behavior has been observed using non-equilibrium capacitance-time (C-t) and current-time (I-t) measurements, at room temperature and at 400degC.
