![]() | Vardeny, Zeev Valentine | Picosecond trapping of photocarriers in amorphous silicon | Trapping of photoexcited carriers in the picosecond and subnanosecond time domains was studied by measuring the decay of photoinduced absorption (PA) in a-Si, a-Si:F, a-Si:H, and a-Si:H:F. We found that when the midgap density of states decreases, both the trapping time and its temperature dependenc... | Photocarriers; Amorphous silicon; Picosecond trapping; Photoinduced absorption | 1983 |
