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.

Graphene nanoribbon bandstructure
17 Apr 2010 | | Contributor(s):: Saumitra Raj Mehrotra, Gerhard Klimeck
Graphene nanoribbons (often abbreviated as GNR) are planar strips of graphene with a thickness of approximately one atom. Carbon atoms in graphene are sp2-hybridized with a carbon-carbon bond length of approximately 0.142 nm. As an electronic material, graphene exhibits many desirable...

Crystal Viewer Demonstration: Various Crystal Systems
This video shows the use of the Crystal Viewer Tool to visualize several crystal systems, including Si, GaAs, C60 Buckyball, and a carbon nanotube. Crystal systems are rotated in 3D, zoomed in and out, and the lattice style changes from sticks and balls to lines to spheres.
