Abstract

Photogenerated carrier dynamics in undoped a-Si:H have been studied by photoinduced absorption (PA), photoluminescence (PL) and their respective optically detected magnetic resonances: PADMiR and PLDMR. We have detected for the first time the “g = 4” resonance in PADMR, in addition to the previously measured narrow and broad resonances at g≈2. We compare the PADMR and PLDMR resonances over a broad spectral range of detection energies and conclude from the similarities that they share a common underlying mechanism. The PADMIR spectra of the narrow and the broad resonances at g≈2, measured in the spectral range of 0.7 to 1.7 eV, suggest that a correlation exists between the two resonances and PA.
