Photogenerated carrier dynamics in undoped a-Si:H have been studied by photoinduced absorption (PA), photoluminescence (PL) and their respective optically detected magnetic resonances: PADMR and PLDMR. The authors have detected for the first time the g= 4 resonance in PADMR, in addition to the previously measured narrow and broad resonances at g {approx} 2. They 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 PADMR spectra of the narrow and the broad resonances at g {approx} 2, measured in the spectral range of 0.7 to 1.7 eV, suggest that a correlation exists between the two resonances and PA.
