Abstract
Under constant current conditions, an Stype current/voltage characteristic has been observed for thin platelets of photoconducting CdS at room temperature. Evidence is presented which shows that the nonohmic behaviour is associated with excitation of vibrational modes of the platelet. The origin of the negative differential resistance is discussed using a simple model.Keywords
