Phonon-induced linewidths of graphene electronic states
(2018) In Physical Review B 98(20).- Abstract
The linewidths of the π and σ bands originating from the electron-phonon coupling in graphene are analyzed based on model calculations and experimental angle-resolved photoemission spectroscopy (ARPES) data. We find evidence for crucial contributions to the lifetime broadening from interband scattering π→σ and σ→π, respectively, driven by the out-of-plane ZA acoustic phonons. The essential features of the calculated σ band linewidths are in agreement with recent published ARPES data [Mazzola, Phys. Rev. B 95, 075430 (2017)2469-995010.1103/PhysRevB.95.075430] and of the π band linewidth with ARPES data presented here.
