Abstract

We present room temperature measurements on the electron drift velocity in hydrogenated amorphous silicon (a-Si:H) for large electric fields (1.3 × 105 to 3 × 105 cm/s). The experimental time resolution was ˜ 1ps and velocities as high as 8 × 105 cm/s were observed. The electron transport was non-dispersive, and the velocity was found to be a superlinear function of the applied field.
