Abstract

Identifying constituent atoms in materials is the ultimate goal for all analytical techniques. Here, we describe the successful achievement of single atom spectroscopy in nanostructured carbon-based materials using a scanning transmission electron microscope equipped with electron energy-loss spectroscopy. The chemical analyis of individual metallofullerene molecules can be successfully performed without massive beam damage. Atom-by-atom spectroscopy of the edge carbon atoms in single layer graphene is also discussed.
