Paper Abstract

Nonlinear photoinduced absorption of hydrogenated amorphous silicon (a-Si:H) was studied by excitation spectroscopy. The experimentally obtained excitation spectra are in compliance with the spectra of unperturbed absorption in 1.2 - 3.2 eV spectral range. The applicability of the method for the absorption coefficient measurement in broad range of 1 - 105 cm-1 (1 micrometers film) is demonstrated. A proposed model of photoinduced absorption from localized states is discussed.
