Graphene 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.

Salvador Barraza-Lopez, assistant professor of physics, Markus Kindermann of Georgia Institute of Technology and M. Y. Chou of Georgia Tech and the Academia Sinica in Taiepi, Taiwan, report their findings in NanoLetters.

"If you want to use graphene for devices, you want to understand what will happen with metal contacts," Barraza-Lopez says. . .View Full Article
