Abstract

A study of 100 keV Co⁺-implanted C₆₀ films with Rutherford Backscattering and Raman spectroscopy has revealed the pronounced cobalt translation from the surface layer of amorphous carbon into the deeper crystalline fullerene due to post-implantation annealing at 300 °C. Carbon density gradient along the film depth is discussed as a driving force of this effect. Cobalt deficit in the doped fullerene layer, detected by means of ion beam analysis, suggests ionization of the C₆₀ molecules under the collisions with 2 MeV He⁺ ions.
