摘　　要：We report on the formation of a graphene monolayer on a Ru（0001） surface by annealing the Ru（0001） crystal. The samples are characterized by scanning tunnelling microscopy （STM） and Auger electron spectroscopy （AES）. STM images show that the Moire pattern is caused by the graphene layer mismatched with the underlying Ru（0001） surface and has an N × N superlattice. It is further found that the graphene monolayer on a Ru（0001） surface is very stable at high temperatures. Our results provide a simple and convenient method to produce a graphene monolayer on the Ru（0001） surface, which is used as a template for fabricating functional nanostructures needed in future nano devices and catalysis.We report on the formation of a graphene monolayer on a Ru（0001） surface by annealing the Ru（0001） crystal.
