Abstract

The theory of trap-controlled dispersive transport based on exponential band-tail traps is extended to include the saturation of trap occupancy at high excitation levels. The absence of saturation effects in the transient photocurrent experiment of Hvam and Brodsky is shown to contradict the band-tail hypothesis of this model.
