Title: | Electron-phonon coupling in graphene | Authors: | Milošević, Ivanka Kepćija, Nenad Dobardžić, Edib Damnjanović, Milan Mohr, Marcel Maultzsch, Janina Thomsen, Christian |
Keywords: | Electron-phonon interaction;Graphene;Kohn anomaly;Symmetry | Issue Date: | 20-Mar-2010 | Journal: | International Journal of Modern Physics B | Abstract: | Numerical and symmetry based analysis of the electron-phonon coupling in graphene have been performed. Symmetry alone predicts the Kohn anomalies, their positions in the Brillouin zone and all quantum numbers of the Kohn modes and the vectors of the Kohn displacements. Dispersion of kink phonons is calculated and found to be similar to the classical phonon spectrum. Interestingly, most of the Γ (including all the acoustic phonons as well) and K modes are shown to be uncoupled to electrons. © 2010 World Scientific Publishing Company. |
