Large area graphene sheets
A rapidly increasing list of production techniques have been developed to enable graphene's use in commercial applications. Isolated 2D crystals cannot be grown via chemical synthesis beyond small sizes even in principle, because the rapid growth of phonon density with increasing lateral size forces 2D crystallites to bend into the third dimension. In all cases, graphene must bond to a substrate to retain its two-d… WebbGraphene sheets, if fully exposed and reasonably large, have a theoretical surface area of 2,629 m2/g.
