 | Vardeny, Zeev Valentine | Photoinduced absorption spectra in amorphous Si:H and Ge:H and microcrystalline Si:H | The steady state subgap photoinduced absorpotion bands in a-Ge:H and a-Si:H are interpreted in terms of two kinds of optical transitions of photoexcited carriers from traps in the gap into the bands of which one produces absorption and the other produces bleaching. The photoinduced absorption in mic... | Photoinduced absorption; Si:H; Ge:H; Amorphous silicon; Amorphous germanium; Microcrystalline silicon | 1984 |
