Abstract:

We have extensively explored near zero field magnetoresistance (NZFMR) effects, due to spin-dependent recombination, spin-dependent charge pumping and spin-dependent trap-assisted tunneling in devices that have been irradiated or have undergone electrical stress to mimic the effects of radiation. We have correlated the amount of stress to the defect density and effects on NZFMR. In addition to Si MOSFETs we have conducted studies of amorphous hydrogenated silicon and silicon nitride films, aluminum oxide gate oxides, and SiC MOSFETs.
