Abstract:
The ability of a neutral diamagnetic twofold-coordinated silicon atom with two paired electrons (=Si: silylene center) in SiO2 to capture charge carriers is investigated by the ab initio density-functional method. It is found that this defect is a hole trap in SiO2. Hole trapping brings about the formation of paramagnetic twofold-coordinated silicon atoms with an unpaired electron =Si·. According to this prediction, the silylene center and the silicon-silicon bond can be responsible for the accumulation of the positive charge in metal-oxide-semiconductor structures under ionizing radiation.
