Metal wires of carbon complete toolbox for carbon-based computers: Metallic carbon circuit element enables work on faster, efficient carbon-based transistors

Carbon-based computers have the potential to be a lot faster and much more energy efficient than silicon-based computers, but 2D graphene and carbon nanotubes have proved challenging to turn into the elements needed to construct transistor circuits. Graphene nanoribbons can overcome these limitations, but to date scientists have been made only semiconductors and insulators, not the metallic wires to connect them. UC Berkeley scientists have now achieved the goal of a metallic graphene nanoribbon.
