The group of Eva Andrei, along with collaborators from Belgium and Japan, have discovered a new way to control and guide electrons in graphene by removing a single carbon atom from its perfect honeycombed lattice

ea16 They showed that the vacancy can stably host a local charge which traps electrons in satellite orbits, resembling a tunable artificial atom.

This is the first observation of a stable and tunable charged vacancy in graphene and could potentially lead to the fabrication of artificial atom arrays for performing the electronic equivalent of optical operations.
