Graphene plasmonics

Abstract

Two rich and vibrant fields of investigation - graphene physics and plasmonics - strongly overlap. Not only does graphene possess intrinsic plasmons that are tunable and adjustable, but a combination of graphene with noble-metal nanostructures promises a variety of exciting applications for conventional plasmonics. The versatility of graphene means that graphene-based plasmonics may enable the manufacture of novel optical devices working in different frequency ranges - from terahertz to the visible - with extremely high speed, low driving voltage, low power consumption and compact sizes. Here we review the field emerging at the intersection of graphene physics and plasmonics. © 2012 Macmillan Publishers Limited. All rights reserved.
