Abstract

Local electronic structures of C₆₀-Co mixture films were studied by X-ray photoelectron spectroscopy (XPS) and near-edge X-ray absorption fine structure (NEXAFS) spectroscopy. XPS spectra of the C₆₀-Co films show binding energy shifts and broadenings compared to those for a pure C ₆₀ film in the C1s main and satellite peaks. XPS spectra in the valence region suggest an appearance of new components at near the Fermi level. NEXAFS spectra of the C₆₀-Co film also show small shifts and broadenings of absorption peaks at C 1s → π^* excitations. These results are attributed to the formation of hybridized molecular orbitals with a back donation between Co 3d and C₆₀ π orbitals.
