Popis: It was found that light-soaked and thermally-quenched a-Si:H films with the same density of neutral dangling bonds, D0 (3×1016 cm−3 including the surface defects) have different light-induced ESR spectra and different dark- and photoconductivities. We carried out the light-soaking for these two films and found that the D0-creation rate for the thermally-quenched film is larger than that for the light-soaked film. From these results, we conclude that the Si–Si weak bond plays a role of the photocreation of D0.
