image: Frictional domains on a monolayer graphene. AFM topography (left), simultaneously obtained friction force image (center), and predicted ripple domains (right) of an exfoliated monolayer graphene on SiO2. This image relates to an article that appeared in the June 30, 2011, issue of Science Express, published by AAAS. The study, by J.S. Choi of Konkuk University in Seoul, Korea, and colleagues was titled, "Friction Anisotropy-Driven Domain Imaging on Exfoliated Monolayer Graphene." view more
