Abstract

Selenium materials such as used for xerographic machines can be very sensitive to temperature changes. Much of the sensitivity is due to increased dark current leakage through the photo- receptor material which is generally exponential with increases in temperature. The ideal photoreceptor, among other properties, should exhibit zero dark current,
