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.

    02 Mar 2015 | | Contributor(s):: Ian Appelbaum

    Despite its low atomic number and inversion symmetry, recent electronic measurements demonstrate that (group-IV) graphene has a greatly disappointing spin lifetime, corroborated by theory showing strong spin-flip scattering by flexural (out-of-plane) phonons. There exists a class of graphene-like...
