Résumé

Different spatially resolved electron energy-loss spectroscopy (EELS) experiments on individual nanotubes performed in the context of a scanning transmission electron microscope (STEM) are presented. The capabilities of EELS for probing the local anisotropy of the unoccupied electronic states are demonstrated and the effects of the graphite network curvature on the nature of the chemical bonding is investigated. The peculiarity of the valence electron excitation modes in carbon nanotubes due to the curved anisotropy is also pointed out through near-field EELS experiments.
