WebDec 12, 2024 · The recent ability to manipulate graphene-like structures at the atomic scale is opening up new challenges in electronics and photonics, with a key focus on the bulk and edges of the systems, which generate peculiar and interfering charge density oscillations, quantized as plasmons. These quasiparticles are here scrutinized in planar periodic … WebOct 15, 2024 · For example, when we consider a graphene nanoribbon, which is a 1D graphene with two edges, “edge plasmon” is excited at one of the edges [[12] ... The surface plasmon in graphene is important for application of a signal-transmission device since (1) the surface plasmon can propagate a sufficiently long distance ...
Surface plasmons in graphene and carbon nanotubes
WebOct 6, 2024 · Tunable surface plasmon resonance-based graphene nanoribbon (GNR) terahertz (THz) polarizers with adjustable operating frequency are proposed in this work. While conventional THz polarizers lack robustness and tunability, recently reported graphene-based metastructure polarizers have complex fabrication processes and … WebJan 22, 2024 · In this work, we explore the possibility of trapping free-gas molecules via surface adsorption, optical, or electrostatic fields to enhance gas-plasmon interactions and to increase plasmon-sensing ability. We discuss the relative strengths of these trapping forces and find gas adsorption in a typical nanoribbon array plasmonic setup produces ... chili\u0027s three for me $10 meals
