“It’s terrific that top-flight physicists are pursuing this,” said Lettow. “But graphene is not just an academic exercise. It will have a big, immediate commercial impact.” Lettow graduated from Princeton Engineering in 1995 and did his senior thesis with Aksay.
Lettow said that graphene is likely to eclipse carbon nanotubes, one of the hottest areas of nanotechnology. Graphene promises many of the same exciting applications as carbon nanotubes, which are costly and difficult to manufacture.
Graphite, the most stable form of carbon on Earth, consists of many layers of graphene. Through a chemical process, Aksay and Prud’homme explode graphite into ultrathin individual sheets of graphene. The image above, captured by postdoctoral researcher Hannes Schniepp with an atomic force microscope, shows about 20 sheets of graphene. Each sheet is only a couple of nanometers high and 200 to 500 nanometers wide (to put this in perspective, the average human hair is about 40,000 nanometers wide).
Aksay and Prud’homme have collaborated in their graphene work with Princeton professor of chemistry Roberto Car, Princeton associate research scholar Je-Luen Li, and Konstantin Kudin, an associate research scholar at the Princeton Institute for the Science and Technology of Materials. More information on Princeton's graphene-related research is available at the Ceramic Materials Laboratory. Read more about Vorbeck's products and history.
