Abstract

The photo-field effect has been measured between 4.2K and 300K using an a-Si thin film transistor. The data are fit self-consistently taking full account of changes in space charge, photo carrier drift, diffusion and recombination. Gap state density and capture cross sections are fitting parameters. Evidence for tunnel recombination is found. Electron localization radius was found to be 13Å.
