Published work on conductance fluctuations in hydrogenated amorphous silicon is surveyed. There are many reports of 1/f noise, some describing unusual features such as non-Gaussian statistics. The relative insensitivity to doping and temperature highlighted. In addition the random-telegraph-like noise often reported. successes failures generation–recombination models for current filament telegraph summarised.
