▎ 摘　　要

We have prepared Ca-intercalated multilayer epitaxial graphene films on silicon carbide and observed superconductivity in them with both magnetic and transport measurements. Superconducting transition has been detected at temperature up to 7K in Ca-intercalated epitaxial graphene with the thickness down to 10 layers grown on both Si-face and C-face of silicon carbide. The result demonstrates intercalated epitaxial graphene as a good platform to study graphene-based superconductivity. (C) 2013 AIP Publishing LLC.
