Description

Graphene is a one-atom-thick planar sheet of sp2-bonded carbon atoms that are densely packed in a honeycomb crystal lattice. The term Graphene was coined as a combination of graphite and the suffix -ene by Hanns-Peter Boehm, who described single-layer carbon foils in 1962. Graphene is most easily visualized as an atomic-scale chicken wire made of carbon atoms and their bonds. The crystalline or "flake" form of graphite consists of many graphene sheets stacked together.

    Online Presentations | 20 Dec 2011 | Contributor(s):: Eric Pop

    This talk will present recent highlights from our studies of dissipation in novel nanoelectronics based on graphene and phase-change materials. We have investigated both Joule heating and Peltier cooling in graphene electronics, and found that the latter could be tuned to partially remove the...
