    Phosphorus-doped and boron-doped hydrogenated amorphous silicon were studied by photoinduced absorption (PA) in the time range from 2 to 1800 ps. Prolonged light exposure (hω=2.0 eV) causes PA to decay more rapidly. The data are fit to a multiple trapping model. Minority carriers get trapped...

    Annealing of metastable dangling bond defects in light-soaked undoped hydrogenated amorphous silicon (a-Si:H) is investigated in samples which have been illuminated at different temperatures. Based on a monomolecular annealing model, the distribution of activation energies is determined. The...
