Abstract
Experimental transient photoconductivity in a-Si:H and mu c-Si: H is analysed by a Fourier Transform technique to reveal a relative density of states. It is often found that a deep-lying structure probably associated with defects, at around 0.5 - 0.6 eV depth exhibits an apparent shift against the background of band-tail states as the temperature is varied. We investigate by numerical modelling whether this shift arises from differential attempt-to-escape frequencies in a multi-trapping context, or from a temperature - dependent hopping transport energy.
