Résumé

It is shown that the anomalous band in dual-beam CPM (DBCPM) spectra of a-Si:H results from a combination of two processes: photocurrent enhancement due to excitations by the probe light from the valence band to the D⁺ states, and photocucurrent reduction due to excitations by the probe light from the D⁰ states to the conduction band. Using the DBCPM spectra, we measured the optical transition energy (0.77 eV) and the electron correlation energy (0.16 eV) for the filled D^- defects.
