Graphene is a single layer of graphite with a hexagonal structure, or an individual sheet of sp 2-hybridized carbon bound in two dimensions. It was experimentally fabricated for the first time through mechanical ex foliation of small mesas from highly oriented pyrolytic graphite (HOPG) in 2004 and subsequently was found with excellent electrical properties (Novoselov et al., 2004). This discovery has triggered enormous amount of interest on graphene both in fundamental and applied research. Graphene has shown promising applications as ultra-sensitive gas sensors, transparent electrodes in liquid crystal display devices, and large capacity electrodes in Li batteries (Rao et al., 2009).
