Bias-induced conductivity changes in a-Si:H are reported.
In contrast with the bias effects on doped and multilayered a- Si:H undoped a-Si:H shows the increase of conductivity nearly an order of magnitude sample degradation after cooling with 200V(3000 V/cm)from 200℃. We try to interpret these changes as a result of bias-induced deep trap centers.
