It is observed that Si–H stretching mode vibrational spectra in porous silicon and in hydrogenated amorphous silicon: (i) is broad with a full width at half maxima of ≈20-40 cm -1; (ii) has a long low energy tail; and (iii) has a peak value shifted by 100 cm -1 from 2000 cm -1 (crystalline silicon case) to 2100 cm -1. We propose a simple phenomenological model to account for the above features. The model invokes a narrow distribution in the Si–H bond distances. The first feature namely the broadening can be satisfactorily explained. Although our model yields a low energy tail, it is not as pronounced as the experimental tail. Our model can be shown to be consistent with the third feature, namely the peak shift.

AbstractHigh rate deposition of high quality and stable hydrogenated amorphous silicon (a-Si:H) films were performed near the threshold of amorphous to microcrystalline phase transition using a very high frequency plasma enhanced chemical vapor deposition (VHF-PECVD) method. The effect of hydrogen dilution on optic-electronic and structural properties of these films was investigated by Fourier-transform infrared (FTIR) spectroscopy, Raman scattering and constant photocurrent method (CPM). Experiment showed that although the phase transition was much influenced by hydrogen dilution, it also strongly depended on substrate temperature, working pressure and plasma power. With optimized condition high quality and high stable a-Si:H films, which exhibit σph/σd of 4.4×106 and deposition rate of 28.8Å/s, have been obtained.
