摘要

As a one-atom-thick two-dimensional crystal, graphene has been considered a basic building block for all sp~2 carbons including fullerene, carbon nanotubes, and graphite. Since Geim et al. peeled a few graphene sheets from highly crystalline graphite by a 'scotch tape' method in 2004, some unique electronic properties of this conceptual matter, such as chiral quantum Hall effects and charge-carriers independent conductivity, have been found, which indicate potential applications in quantum devices, nanocomposites with various matrixes, and ultrathin membrane materials. Many approaches have been developed to prepare graphene materials, mainly including micromechanical cleavage of highly oriented pyrolytic graphite (HOPG), sublimation of silicon from silicon carbide, and some chemical methods.
