1 Vardeny, Zeev ValentineOptical picosecond studies of hot carriers in amorphous semiconductorsThermalization of photogenerated carriers in a-Si, a-Si:H, a-As2Se3 and a-Se was studied by measuring the photoinduced absorption with subpicosecond resolution. The thermalization process can be described by Frohlich interaction with polar phonons in a-Si:H and a-As2Se3 but not in a-Si. Using photo...Photogenerated carriers; Thermalization1981-10

3 Vardeny, Zeev ValentinePicosecond dynamics of carriers in amorphous semiconductorsUsing 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 geminat...Excess carriers; Thermalization1981-10
4 Vardeny, Zeev ValentineTime resolved spectroscopy of photoinduced absorption in glow-discharge a-Si:HThe time and temperature dependence of the photoinduced absorption spectra was measured in glow-discharge a-Si:H in the energy range 0.7 to 1.4 eV, temperature interval 10 to 306K and time domain 2 ys to 2 ms. The results are consistent with a model based on thermalization of excess carriers in tra...Photoinduced absorption; Glow-discharge a-Si:H; Thermalization; Excess carriers; Trap states; Time dependence; Temperature dependence1981-10
