Structural ordering in amorphous silicon thin film due to post hydrogen plasma annealing

摘要

The effect of hydrogen plasma annealing on the microstructural transition from disorder to order in amorphous silicon film is studied in this paper. Combined with the Fourier Transmit Infrared spectroscopy, Raman scattering and absorption spectra, it is found that there exists two steps for the reaction between atomic hydrogen and Si network. It is shown that the hydrogen plasma treatment conditions strongly influence the microstructures of the amorphous Si films.
