In recent years, we have seen a rapid progress in the field of graphene plasmonics, motivated by graphene's unique electrical and optical properties, tunability, long-lived collective excitation and its extreme light confinement. Here, we review the basic properties of graphene plasmons: their energy dispersion, localization and propagation, plasmon-phonon hybridization, lifetimes and damping pathways. The application space of graphene plasmonics lies in the technologically significant, but relatively unexploited terahertz to mid-infrared regime. We discuss emerging and potential applications, such as modulators, notch filters, polarizers, mid-infrared photodetectors, and mid-infrared vibrational spectroscopy, among many others.

Novel effects of strains in graphene and other two dimensional materials (2015, background): “e described by treating electron-electron interactions within the random phase approximation (RPA) [331]. In the long wavelength limit ~!˝2E F, the plasmon dispersion reads !(~k) = 2ckE F=~ 1=2 (93) [332,333,13]. For typical graphene-on-substrate samples, E F is of the order of 0:5eV or lower. This ”
