| Outline of Final Research Achievements |
Recently, monolayer graphite (graphene) with Dirac electrons has attracted much attention because it shows various interesting physical properties. On the other hands, the detailed electronic structure depended on the number of layers in graphene related materials has not been well understood yet. In this work, I have fabricated the thinnest limit of graphite intercalation compounds (intercalated bilayer graphene) and elucidated its electronic structures by high-resolution ARPES. In Ca intercalated bilayer graphene, I clearly observe the interlayer band responsible for superconductor in bulk GICs, suggest that Ca intercalated bilayer graphene also may show the 2-dimentional superconductivity. Additionally, I find the substrate-induced charge density wave in π band on Ca intercalated bilayer graphene.
