Abstract

The transport of a pulse of photogenerated excess electrons has been investigated in a-Si p+-i-n+ junctions under forward bias in the presence of strong double injection. It is found that the electron drift mobility is completely independent of forward current densities of up to 0.33 Acm−2, in disagreement with the work of Silver et al. We suggest that the experimental disagreement arises from problems inherent in the voltage step technique of mobility measurement.
