Two kinds of centers with different barrier heights contribute to the Poole-Frenkel current in a-SiN0.7:H in a high electric field. Based on the characteristics of these centers, a field enhancement of photocurrent was expected and actually observed in the field where the Poole-Frenkel current flows in the dark. This phenomenon is due to field-assisted thermal ionization of the shallow center, which is occupied under the photoexcitation.
