DOI: 10.1109/tns.2020.3004710
Abstract: The p-n-p bipolar junction transistors (BJTs) are susceptible to surface recombination in both the emitter-base depletion and neutral base (NB) regions when their passivation oxide layers are damaged by ionization irradiation, leading to an increase… read more here.
