摘要
This paper discusses mechanisms for defect metastability with H atom participation at Si-SiO2 interfaces as in field effect transistors. Reaction pathways are associated with differences in defect bonding properties between positively charged (i) Si atoms and (ii) O and N atoms, Defect reaction equations, supported by quantum chemistry calculations. are presented. The metastable defects emphasized here are created by hole trapping followed by H atom attachment.
