Abstract
We employ transient photocurrent decay measurements to determine the d istribution of conduction band tail states in hydrogenated amorphous s ilicon. It is found that these experimental results suggest the possib ility of deviations from a single-exponential functional form. This is consistent with other more recent experimental determinations of the distribution of conduction band tail states in hydrogenated amorphous silicon. (C) 1997 Elsevier Science Ltd.
