Microscopy reveals 'atomic antenna' behavior in graphene

Atomic-level defects in graphene could be a path forward to smaller and faster electronic devices. With unique properties and potential applications in areas from electronics to biodevices, graphene, which consists of a single sheet of carbon atoms, has been hailed as a rising star in the materials world. Now, a new study suggests that point defects, composed of silicon atoms that replace individual carbon atoms in graphene, could aid attempts to transfer data on an atomic scale by coupling light with electrons.
