characteristics are measured for diffe- rent source-drain voltages and annealing temperatures
indicating properties of the a-Si:H field effect transistor (FET).For samples annealed at 500℃ and in Ar gas
the field effect chara- cteristics in negative gate voltage show a remarkable improvement.It is found from measured data that peaks of N(E) exist at about 0.4eV from the mobility edges in the valence and co- nduction bands.
