Combined xerographic measurements and a delayed‐collection field technique have been applied to a‐Si:H. to determine whether geminate recombination controls the photogeneration process in a‐Si:H. The delayed‐collection field method allows the photogeneration efficiency at low applied fields to be measured. The results show that, depending on sample preparation, the zero‐field quantum efficiency ranges from 0.44 to 0.55. The measured field dependence of the quantum efficiency give best fits to… CONTINUE READING
