Abstract
We have tested the validity of the effective temperature approach in amorphous semiconductors by performing high electric field ( - V/cm) photoconductivity measurements in intrinsic hydrogenated amorphous silicon () films at low temperatures. Our results on thermal quenching in conclusively show that there is an equivalence between electric field and temperature as required by the effective temperature approach for electrons. We find a different functional dependence of the electron effective emperature on the actual temperature and field from the one previously proposed. We propose that a similar effective temperature can be formulated for holes.
