Abstract
We present electron energy-loss spectroscopy studies in transmission of the electronic structure of (C59N)2. The overall broadening observed for the π-derived structures in the low energy-loss function of (C59N)2 when compared to C60 is due to the reduced symmetry of the heterofullerene. The optical gap of (C59N)2 is about 1.4 eV, slightly smaller than that of C60 (1.8 eV). Using a Kramers-Kronig analysis the dielectric function in the low energy region was calculated. A static dielectric function at zero energy of ∼ 5.6 is found.
