Raman Spectroscopy Characterization of Ion-beam-modified Polyimide Films

摘要

Raman spectroscopy was employed in studying the effects of irradiation conditions on the structural modifications of irradlated polyimide films. A decomposing approach of data analysis for the experimental Raman spectra demonstrates that the implantation conditions play important but different roles in the formation of the final structures. A calculation was also performed to find out the contribution from the phonon state density of amorphous graphite to the Raman spectrum profiles.
