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.

How to Turn Graphene into a Robust Topological Insulator Using Adatoms
12 Jul 2011 | | Contributor(s):: Jason Alicea
In this talk I will discuss a recent proposal for generating a robust TI state in a more readily available two-dimensional system -- graphene.
Levitated Spinning Graphene
18 Jan 2011 | | Contributor(s):: Bruce E. Kane
I will describe a method for levitating micron-sized few layer graphene flakes in a quadrupole ion trap. Starting from a liquid suspension containing graphene, charged flakes are injected into the trap using the electrospray ionization technique and are probed optically.
Translational Research in Nano and Bio Mechanics
18 Nov 2010 | | Contributor(s):: Ken P. Chong
One of the most challenging problems is the integration and interface between wet (biological) and dry (structural) materials. Nano and bio science and engineering is one of the frontiers in transformative and translational research. The transcendent technologies include nanotechnology,...
Chemically Enhanced Carbon-Based Nanomaterials and Devices
09 Nov 2010 | | Contributor(s):: Mark Hersam
Carbon-based nanomaterials have attracted significant attention due to their potential to enable and/or improve applications such as transistors, transparent conductors, solar cells, batteries, and biosensors. This talk will delineate chemical strategies for enhancing the electronic and optical...
Nano*High: X-rays, Lasers, and Molecular Movies
25 Sep 2010 | | Contributor(s):: Roger W. Falcone
X-ray imaging is an excellent method to make visible what would normally be invisible - who hasn't had an X-ray at the doctor or dentist's office before? At the Lawrence Berkeley National Lab, the Advanced Light Source is a gigantic X-ray imaging machine. Dr. Roger Falcone discusses X-ray...
Ripples and Warping of Graphene: A Theoretical Study
08 Jun 2010 | | Contributor(s):: Umesh V. Waghmare
We use first-principles density functional theory based analysis to understand formation of ripples in graphene and related 2-D materials. For an infinite graphene, we show that ripples are linked with a low energy branch of phonons that exhibits quadratic dispersion at long wave-lengths. Many...
Surface Characterization Studies of Carbon Materials: SS-DNA, SWCNT, Graphene, HOPG
16 Feb 2010 | | Contributor(s):: Dmitry Zemlyanov
In this presentation examples of surface characterization studies of carbon specimens will be presented. (1) In particularly, the systematic XPS (X-ray photoelectron spectroscopy) characterization of graphene grown on the SiC surface will be reported. This work demonstrates a use for XPS to...

Nano Carbon: From ballistic transistors to atomic drumheads
14 May 2008 | | Contributor(s):: Paul L. McEuen
Carbon takes many forms, from precious diamonds to lowly graphite. Surprisingly, it is the latter that is the most prized by nano physicists. Graphene, a single layer of graphite, can serve as an impenetrable membrane a single atom thick. Rolled up into a nanometer-diameter cylinder--a carbon...
The Novel Nanostructures of Carbon
28 Feb 2008 | | Contributor(s):: Gene Dresselhaus
A brief review will be given of the physical underpinnings of carbon nanostructures that were developed over the past 60 years, starting with the electronic structure and physical properties of graphene and graphite, and then moving to graphite intercalation compounds which contained the first...
