Abstract

We have measured the transient photocurrent in “time-of-flight” structures of a-Si:H using bias voltages applied following photocarrier generation by a laser flash. The delayed field technique appears promising both as a probe of the deep level distribution and also of photocarrier thermalization. We describe a simplified theory for the delayed field transients including the effects of the delay time and the magnitude of the applied voltage. The theory accounts for the measurements adequately.
