Effects of curvature on the electronic transport in graphene — •Sebastian Gattenlöhner¹, Mikhail Titov², and Wolfgang Belzig¹ — ¹Fachbereich Physik, Universität Konstanz — ²School of EPS - Physics Department, Heriot-Watt University Edinburgh

As was recently shown experimentally [1], free-standing graphene is not entirely flat but is intrinsically curved. The low-energy electronic excitations in graphene can be described by a Dirac-like Hamiltonian, where the curvature manifests itself in form of additional vector and scalar potentials. We study the effect of these potentials on the electronic transport properties of graphene.
