 | Mattis, Daniel C. | Mobility gap and anomalous dispersion | It is shown that anomalous dispersion of quasiparticles leads to nonpropagating states. Therefore regions of anomalous dispersion define a sort of "mobility gap." Using the coherent-potential approximation, we calculate the conditions for obtaining such a mobility gap in a disordered binary alloy.

 | Vardeny, Zeev Valentine | States in the gap of doped and undoped a-Si:H studied by the photomodulation spectroscopy | The steady state photomodulation spectrum, its temperature and excitation intensity dependences have been studied in phosphorous doped and undoped a-Si:H. The spectra are analyzed in terms of photocarriers trapped in band-tail states and dangling bonds (DB) defects in undoped samples and impurities ... | Doped a-Si:H; Undoped a-Si:H; Amorphous silicon; Photomodulation spectroscopy; Mobility gap; Steady state photomodulation spectrum | 1987 |
