Modification of C $_{60}$ thin films by ion irradiation

Narumi, Kazumasa; Naramoto, Hiroshi

Irradiation effect of 7 MeV $^{12}$ C $^{2+}$ ions on C $_{60}$ thin films on Si(111) substrates were investigated. Raman scattering spectroscopy showed that C $_{60}$ film had been already polymerized and that depolymerization of the polymerized C $_{60}$ films progressed up to the dose of 1.110 $^{14}$ /cm $^{2}$ . After the depolymerization, the C $_{60}$ 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.
