Defect studies in electron-irradiated boron-doped silicon

Abstract
DLTS and MCTS studies are reported for boron-doped (about 3.5*1015 cm-3) pulled silicon specimens which have been subjected to electron irradiation at 1.5 MeV at about 80 K. A number of previously reported and identified features are observed and two new peaks are reported, the first possibly dependent on oxygen content at an energy level of about Ev+0.13 eV and with a capture cross section of about 10-18 cm2, the second with a charge-dependent peak amplitude at an energy of Ev+0.34 eV-apparently a vacancy-dependent complex annealing out at around room temperature.
