Kohn anomalies in graphene nanoribbons

Kohn anomalies in graphene nanoribbons

The quantum corrections to the energies of the Γ point optical phonon modes (Kohn anomalies) in graphene nanoribbons (NRs) are investigated. We show theoretically that the longitudinal optical (LO) modes undergo a Kohn anomaly effect, while the transverse optical (TO) modes do not. In relation to Ra...
