Energy levels in electron irradiated n-type germanium

Abstract
Deep levels introduced by room temperature 1 MeV electron irradiation in p+n photodiodes have been studied using deep level transient spectroscopy. Two electron traps and one hole trap have been observed after irradiation. A second hole trap is observed upon the annealing of the first hole trap. The energy levels associated with these traps, their cross-sections and their annealing behaviour have been determined
