摘要
Post-deposition treatment of hydrogenated microcrystalline silicon (mu c-Si:H) was carried out using a hot wire in atmospheres of N-2, N-2/H-2 or H-2 and the states of the bonds in the mu c-Si:H films were investigated using X-ray photoelectron spectroscopy. For the mu c-Si:H film treated in N-2 at the filament temperature (T-f) of 1600 degrees C a weak N1s peak was observed. It increased slightly with increasing T-f from 1600 to 1900 degrees C and increased dramatically with increasing T-f from 1900 to 2000 degrees C. The N1s peak of the pc-Si:H film treated in N-2/H-2 at T-f = 2000 degrees C was one order of magnitude lower than that in N-2 at T-f = 2000 degrees C These findings indicate that N-2 molecules decompose on the heated filament and that the addition of H-2 prevents N-2 decomposition.
