Abstract
Measurements of loss factor and capacitance made on single crystals of P-doped n-type silicon are reported. Samples are irradiated with (1.00 ± 0.20) MeV electrons at temperatures <12K. The production of divacancies in the irradiated samples is monitored using hopping conductivity changes at 4.2 K. Higher divacancy production is observed in Czochralski-grown samples and samples containing appreciable concentrations of group III impurities. This suggests that oxygen and group III impurities trap the self interstitials, mobile under irradiation conditions, thus, inhibiting divacancy-self-interstitials annihilation. Effects of irradiation on the free carriers conductivity of the samples are also investigated.
