Abstract
The integrated charge-applied voltage (Q-V) characteristics, voltage induced light waveforms, photo-excitation efficiency and photo-induced capacitance change in SrS:Ce thin films have been studied. Low clamp electric field strength is not an extrinsic characteristic caused by sulphur defect but an intrinsic characteristic caused by Ce doping. Sulphur defects reduce emission intensity generated by recombination of electrons and ionized Ce. Cerium generates deep levels in SrS and acts as a carrier source.
