Gate-Voltage Tunability of Plasmons in Single-Layer Graphene Structures—Analytical Description, Impact of Interface States, and Concepts for Terahertz Devices

The strong light–matter interaction in graphene over a broad frequency range has opened up a plethora of photonics applications of graphene. The goal of this paper is to present the voltage tunability of plasma waves in gated single-layer graphene structures and to quantify their distinction from the plasma waves in ungated graphene struc...More
