Abstract: A new method of photovoltage measurcnment, Field-Modulated Surface Photovoltage Spec-troscopy(FMSPS), has been created by combining the principle of field-effect with the photovoltage technique. Some materials are investigated by using FMSPS. The results show that the method will be helpful to attestation and analysis of surface photovoltage spectroscopy.
