Graphene - electronic structure of an intriguing material

Prof. Karsten Horn
Department of Molecular Physics, Fritz-Haber-Institut der Max-Planck-Gesellschaft, Berlin

Graphene, the single sheet of carbon atoms which is the building block of graphite and carbon nanotubes, has recently attracted a great deal of attention because of its unusual transport properties, which can only be understood on the basis of "massless Dirac Fermion" charge carriers, arising from its unusual band structure. The talk will deal with the electronic structure of graphene as analyzed through valence level photoelectron spectroscopy, and will cover, among other things, the band structure in the monolayer, the transition from true 2D character to the multilayer regime, the specific properties of bilayer graphene, and the influence of many-body excitations on the spectral function of graphene.
