Determination of Drift, Extended State Mobility and Recombination Lifetime in Compensated a-Si:H by Photomixing
Published online by Cambridge University Press: 01 January 1993
Abstract
Mobilities of a series of compensated a-Si:H samples, measured earlier by the time-of-flight technique [1], were determined by the technique of photomixing. We have found that both the extended state and the drift mobilities decrease as the compensation increases. Modelling these transport processes in the context of the photomixing technique, it is shown that long-range potential fluctuations can account for the decrease in the extended state mobility in compensated samples.
