Referat

The electronic 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 sp2 networks and display a pi-band gap at the K point of their 1 x 1 Brillouin zone. Graphene has a distinct Fermi surface which indicates that 0.1 electrons are transferred per 1 x 1 unit cell. Photoemission from adsorbed xenon identifies two distinct Xe 5p1/2 lines, separated by 240 meV, which reveals a corrugated electrostatic potential energy surface. These two Xe species are related to the topography of the system and have different desorption energies.
