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.
