Description:
Author(s): Antonio Politano, Fernando de Juan, Gennaro Chiarello, and Herbert A. Fertig In neutral graphene, two prominent cusps known as Kohn anomalies are found in the phonon dispersion of the highest optical phonon at q = Γ (LO branch) and q = K (TO branch), reflecting a significant electron-phonon coupling (EPC) to undoped Dirac electrons. In this work, high-resolution electron energy … [Phys. Rev. Lett. 115, 075504] Published Fri Aug 14, 2015
