Graphene Plasmonics: Approaching the Intrinsic Lifetime and Modulating a Graphene Plasmonic Resonance at a Few Hundred GHz (Advanced Optical Materials 11/2019)

The front cover shows a low-loss graphene plasmonic resonant device, and its electromagnetic field excited by an incoming THz light. Simulations show good agreement with the experimental results and reveal 100–200 fs plasmon lifetimes, which are approaching the intrinsic lifetime of the graphene plasmon due to the suppression of loss from phonon and edge scattering. For further details see article number 1900315 by Yan Yin, Li Wang and co-workers.
