Terahertz Optoelectronic Property of Graphene: Substrate-Induced Effects on Plasmonic Characteristics

Abstract

The terahertz plasmon dispersion of a multilayer system consisting of graphene on dielectric and/or plasma thin layers is systematically investigated. We show that graphene plasmons can couple with other quasiparticles such as phonons and plasmons of the substrate; the characteristics of the plasmon dispersion of graphene are dramatically modified by the… (More)
