Topography of Graphene on Gold

Caption

Scanning tunneling microscopy shows the topography of graphene on gold with periodic beatings ten times larger than the periodicity of the carbon atoms. These beatings are moiré-patterns, emerging because of the different atomic structures of graphene and the underlying monolayer of gold atoms. The structure of moiré influences chemical interactions between gold and graphene layer and also electronic properties and spin behavior in graphene.
