Graphene Research Could Totally Transform Technologies

9/8/2011 - WRIGHT-PATTERSON AIR FORCE BASE, Ohio -- Air Force Research Laboratory research on graphene, a recently discovered form of carbon, has made a significant contribution to materials development of carbon-based electronics. These efforts improved the understanding of the growth process for both graphene and carbon nanotubes (CNTs) on silicon carbide.
Researchers predict that graphene will be as transformative as the television, atomic bomb, and silicon chip. It has the potential for enormous impact on Air Force capabilities, such as enabling band-hopping radar and leading to radio frequency semiconductors that are 100 times faster than the current state-of-the-art. Graphene may lead to the production of lighter aircraft and satellites, and may be used in sensors, electric batteries, transparent conductive coatings for solar cells, and in a variety of other applications.
Graphene's structure is a one-atom-thick sheet of carbon atoms, most easily visualized as an atomic-scale chicken wire made of carbon atoms at the crossing points and strong covalent bonds connecting them. The crystalline or "flake" form, graphite, consists of many graphene sheets weakly stacked together. A stack of three million graphene sheets would be only one millimeter thick. Graphene exhibits the highest conductivity and other intriguing properties and has been widely popularized as the successor to silicon.
