Abstract
The structure of a single-layer graphene on Ru(0001) is compared with that of a single-layer hexagonal boron nitride nanomesh on Ru(0001). Both are corrugated hybridized networks and display a band gap at the point of their Brillouin zone. In contrast to , has a distinct Fermi surface. Together with the band structure measurements this indicates that per unit cell are transferred from the Ru substrate to the graphene. Photoemission from adsorbed xenon on identifies two lines, separated by 240 meV, which reveals a corrugated electrostatic potential energy surface like on . These two Xe species are related to the topography of the template and have different desorption energies.
