A study of nitrogen doping of graphene reveals the potential of high-resolution electron microscopy for imaging charge transfer around chemical bonds.

The wealth of exceptional properties of graphene stimulates fundamental studies as well as the design of device applications. On the other hand, the material poses real challenges to established characterization techniques, providing an opportunity for improvement that can then be extended beyond this single layer of carbon atoms. For example, high-resolution transmission electron microscopy (HRTEM) can provide otherwise unattainable information on graphene if scientists are prepared to use their sophisticated instruments at their full capability.
