Graphene could someday replace silicon as a semiconductor material and make our chips smaller and faster, except for one tiny detail: it’s been rather hard to mess with its electronic properties. Until now. “We have experimentally realized and theoretically investigated, for the first time, perfect atomic wires in graphene,” Ivan Oleynik, one of the two University of South Florida professors behind the discovery, told Wired.com. Atomic wires are short chains of atoms that conduct electricity and so far, they have been hard to achieve in graphene.
