Several majority and minority peaks with apparent activation energy within a range of 0.6-0.7 eV appeared on the DLTS spectra of Ni

impurity in its different charge states within the doping layers during the zero-reverse bias process have been calculated for the samples.Combining an analysis of the thermal emission rate data of the levels
