Atomic-scale structure of the interface between graphene and SiC(0001) has been investigated using high-resolution transmission electron microscope observation. Our analysis revealed the presence of two types of the interface structure ; one is formed by decomposition of three SiC bilayers, and the other is formed by that of one SiC bilayer. Formation process of graphene layers on SiC is also described.
