Researchers demonstrate how graphene-metal interfaces influence electrons

(Phys.org)—Graphene, an atom-thin layer of pure carbon, appears to have many of the properties needed to usher in the next generation of electronic devices. The next step in building those devices, however, requires creating junctions that connect graphene to the "external world" through at least two metal wires. A "two-terminal junction" is a graphene "ribbon" with two metal contacts. A University of Arkansas researcher and his colleagues have developed a better understanding of how these graphene-metal interfaces affect the movement of electrons through two-terminal junctions.
