This Tiny Electronic Chip Is Just 3 Atoms Thick

These materials could be used to develop electronic displays on windows or windshields, along with powerful microchips in which circuitry spreads not just two-dimensionally but also rises three-dimensionally, the researchers said. For instance, sheets of graphene — a material related to the "lead" in pencils — are each just one carbon atom thick. Graphene is an excellent conductor of electricity, making it ideal for use in wiring.
