Abstract:We observe an anomalous early recovery behavior of base currents in silicon PNP transistors irradiated by 60 Co γ-rays at a dose rate below 1 mrad(Si)/s, which, however, disappears for a higher dose rate. The physical origin of this effect is thoroughly investigated by combining methods of defect concentration measurement, first-principles calculation, and kinetic modeling. The concentrations of interface traps and oxide-trapped charges in these transistors are found to increase monotonically as the total dose… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
