Webthe interface states near the SiC conduction-band edge, which we focus on here, is less clear.11,29,30 The purpose of this work is to look for a possible corre-lation between microscopic defects at the SiO2/SiC interface and the near-interface traps close to the 4H-SiC conduction-band edge. The main emphasis in the microscopy study is on 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. how to spell emmitWebQuasi Steady State Photo Conductance measurements shows a promising effective carrier lifetime of 420 μs, surface recombination velocity of 22 cm/s and a low interface trap density (D(it)) of 4 x 10(11) states/cm2/eV after annealing.
