Abstract: | First order Raman scattering measurements are presented for thin film evaporated a-Se. High temperature films yield polarized and depolarized spectra that are very similar to those of bulk a-Se. Low temperature in situ studied films indicate increased disorder and a considerable reduction in the intensity of the ring attributed 112 cm?1 peak. The Raman spectra of higher temperature films are consistent with a small number of rings and ordered chains that arise from constraints on the dihedral angle. Films deposited at low temperature suggest a reduction in chain order and ring population as might arise from a weakening of constraints on the dihedral angle. |
