Spin-dependent recombination in irradiated Si/SiO2 device structures

Abstract
We report studies of spin‐dependent recombination at the Si/SiO2 interface in electron irradiated (100) and (111) p‐channel metal‐oxide‐silicon field‐effect transistors and metal‐oxide‐silicon wafers. Electron spin resonance transitions on the Pb center increase the recombination current at the Si/SiO2 interface by 2–3 parts in 104. The results are interpreted using a model involving the recombination of electrons and holes at Pb centers with which they are spatially correlated.
