抄録

Massless π bands of graphene grown on a SiC(0001) substrate can be affected by the scattering at the boundaries and the interface superstructure. We investigated the π band structure and width of the single- and double-layer graphenes grown on a vicinal SiC(0001) substrate using angle-resolved photoemission spectroscopy. The π electron scattering at the substrate steps makes the spectrum width anisotropic but no difference occurs in the π band shape. Quasi- 2×2 replicas of the π band due to the interface 6√3×6√3R30°superstructure were observed in the single-layer graphene while they were absent in the double-layer graphene.
