摘要

Low frequency conductance and capacitance measurements have been performed from lHz to 100kHz in the 293-673 K temperature range, on MOS capacitors made on (6H) SiC material. The energy distribution of the trap time constants , capture cross sections and interface state density is presented. The experimental results show that the (6H) SiC-SiO_2 system is qualitatively similar to that of the Si-SiO_2 interface. Conductance measurements performed at high temperature indicate the presence of deep bulk levels.
