Electron-phonon interactions and carrier transport in graphene — •tae yun kim1, nicola marzari2, and cheol-hwan park1 — 1Department of Physics, Seoul National University, Seoul 151-747, Korea — 2Theory and Simulations of Materials (THEOS) and National Center for Computational Design and Discovery of Novel Materials (MARVEL), École Polytechnique Fédérale de Lausanne, 1015 Lausanne, Switzerland
The transport properties of graphene have received much attention partly for its possible applications in electronic devices. In particular, as recently reported, electron-phonon interactions are important in determining the intrinsic carrier transport properties [1,2]. Based on previous studies, we investigate further the carrier transport properties of graphene in terms of carrier density and other physical variables and find connection with experimental results on this matter.
