Dual-Beam Photocurrent Spectra in Undoped a-Si:H
Published online by Cambridge University Press: 01 January 1993
Abstract
It is shown that the anomalous band in dual-beam CPM (DBCPM) spectra results from a combination of two processes: photocurrent enhancement due to excitations by the probe light from the valence baud to theD+ defect states, and photocurrent reduction due to excitations by the probe light from the D° defect states to the conduction band. From the DBCPM spectra, the electron correlation energy for the (filled)D - defects is determined to be 0.25 eV.
