Thickness-Dependent Morphologies of Gold on N-Layer Graphenes

摘要

Since their discovery in 2004, n-layer graphenes have attracted intense interest due to their unique structure; interesting, novel properties; and significant dependence of properties on the layer number "n". For example, in monolayer and bilayer graphene, the carriers correspond to massless and massive Dirac fermions and the quantum hall effect occurs at different filling factors, respectively. In this work we report that gold deposited by thermal evaporation on graphenes interact differently with these substrates depending on the layer number of graphenes.
