Paper Abstract

We present experimental results on the transient response of i/n/i hydrogenated amorphous silicon (a-Si:H) structures as a function of voltage. Comparison with M/i/n devices and results from a novel double-pulse experiment show that the transient current is initially space-charge limited and later limited by emission from deep states in the injecting n layer. Theoretical analysis of these results suggests the existence of a peak in the density of states of As-doped a-Si:H located within 0.3 eV of the conduction-band mobility edge.
