WebJan 18, 2013 · Here we find an epitaxial relationship between graphene and copper foil. Interfacial restructuring between graphene and copper drives the formation of ( n 10) facets on what is otherwise a mostly Cu (100) surface, and the facets in turn influence the graphene orientations from the onset of growth. Webinterfaces, and effects of reconstruction on graphene electronic properties are lacking. In the current work, the mechanism of epitaxial growth of graphene induced Pt(111) surface reconstruction was probed. With the help of particle-swarm optimization algorithm, we found a reconstructed adsorption structure more stable than that proposed before ...
