INTERCALATION OF COBALT UNDERNEATH A MONOLAYER OF GRAPHENE ON Ru(0001)

Scanning tunneling microscopy is used to study intercalation of cobalt underneath a graphene layer on Ru(0001). Deposition of cobalt on graphene/Ru(0001) at 873 K leads to the intercalation of cobalt between the graphene layer and the Ru(0001) substrate, and the intercalation is associated with Co diffusion at steps and defects. The morphology of graphene/Co/Ru(0001) shows moiré pattern, as same as that of graphene/Ru(0001). The bright areas where Co islands exist are hcp regions of graphene/Ru(0001). The intercalated Co islands have a pseudomorphic structure superimposed on Ru(0001).
