Irradiation effect of 7 MeV C ions on C thin films on Si(111) substrates were investigated. Raman scattering spectroscopy showed that C film had been already polymerized and that depolymerization of the polymerized C films progressed up to the dose of 1.110/cm. After the depolymerization, the C films were transformed into a form of amorphous carbon at higher dose. The AFM analysis of conductivity of the film shows the results consistent with the Raman-scattering-spectroscopy analysis of the film.
