Abstract
Negative photoconductivity is studied in Cd1-xZnxS films 8-10 mu m thi ck prepared on glass-ceramic substrates by precipitation from aqueous solutions containing cadmium chloride, zinc chloride, thiourea, and a complexing agent. The films were characterized by spectral, x-ray diff raction, and chemical analyses. Under illumination, the photocurrent f irst rises almost linearly with incident intensity and then saturates. The results are interpreted in terms of a potential barrier for carri er drift.
