| Popis: | The photo-EPR study of semi-insulating GaAs:Cr is reported. For non-irradiated samples the temperature dependence of Cr EPR signal amplitude was measured and the abnormal increasing of the Cr4+ EPR signal at the time the illumination was stopped was discovered. The neutron irradiation suppressed the Cr4+ EPR signal, but had almost no influence on the Cr2+ signal. The gamma irradiation induced a new spectrum. |
