Abstract
Using time resolved photoinduced absorption with subpicosecond resolution we studied hot carrier thermalization followed by deep trapping and recombination in a-Si, a-Si : H, a-Si : F, a-Si : H : F and a-As2Se3. In a-Se and a-As2S3-xSex (0.25 ≤ x ≤ 0.75) the observed relaxations were attributed to geminate recombination.
