Abstract
Low-frequency current oscillations induced by optical quenching were observed in highly photosensitive CdS crystals. No evidence of a negative differential resistivity was found. The current oscillations were observed at room temperature at electric field strengths of 100–800 V/cm. As shown by probe measurements, the instabilities resulted from a bulk phenomenon. The oscillations are related to the excitation of recombination waves, predicted by Konstantinov and Perel.
