ABSTRACT
Since being exfoliated successfully from graphite by Novoselov and Geim in 2004, graphene has attracted tremendous attention in many elds due to the novel and unique electrical, mechanical, thermal, and optical properties,1,2 of which the good optical properties and high carrier mobility of two-dimensional (2D) electrons develop many potential applications in the elds of electromagnetisms and optics, especially in plasmonics.3
