Abstract: "Ultrathin epitaxial graphite was grown on
single-crystal silicon carbide by vacuum graphitization. The material can
be patterned using standard nanolithography methods. The transport
properties, which are closely related to those of carbon nanotubes, are
dominated by the single epitaxial graphene layer at the silicon carbide
interface and reveal the Dirac nature of the charge carriers. Patterned
structures show quantum confinement of electrons and phase coherence
lengths beyond 1 micrometer at 4 kelvin, with mobilities exceeding 2.5
square meters per volt-second. All-graphene electronically coherent devices
and device architectures are envisaged."
