Description

Temperature dependences of the charge-carrier concentration in Czochralski-grown n-Si crystals irradiated with 60Co gamma-quanta are studied. The applicability of a model of the monovalent defect with a level at about Ec - 0.17 eV to the description of the A-center properties in n-Si crystals is analyzed. It is shown that the model is not consistent with available experimental data. It is suggested that the A-center introduces two levels into the upper half of the band gap: an acceptor level in the vicinity of Ec - 0.16 eV and a donor level near Ec - 0.20 eV. This assumption is consistent with the data obtained by magnetic spectroscopy
