Graphene grown epitaxially on SiC has been proposed as a material for carbon-based electronics. Understanding the interface between graphene and the SiC substrate will be important for future applications. We report the ability to image the interface structure beneath single-layer graphene using scanning tunneling microscopy. Such imaging is possible because the graphene appears transparent at energies of +/- 1 eV above or below the Fermi energy (E(F)). Our analysis of calculations based on density-functional theory shows how this transparency arises from the electronic structure of a graphene layer on a SiC substrate.
