Abstract :
In this paper, we present theoretical approach of mechanism of charge storage and transport caused by high electric field polarization or electron beam bombardment in SiO2 grown thermally on Si wafer substrates. The dominant mechanism of charge storage in SiO2 electrets is suggested to be the trapping and drift of injected charges from the upper surface to the bulk oxide. The influence of charge trapping on the surface of SiO2 and Si-SiO2 interface has also been discussed
