Abstract
Gold levels in crystalline Si have been studied by measurement of the phase shift of the modulated photocurrent as a function of temperature and modulation frequency. Three peaks were observed in the phase shift spectra as a function of temperature, two of which are identified with Au donor and acceptor levels, being coincident with previously reported data. The phase shift spectroscopy of the modulated photocurrent can be utilized as a new method for detecting trap levels.Keywords
