WebJun 10, 2024 · The nanowire waveguide is placed in a triangle lattice and the SPP propagation direction is the z axis. Each unit cell carries three nanowires and the diameter of the nanowire is denoted as 2 a. Each nanowire is coated by monolayer graphene, which can be realized by the CVD (chemical vapor deposition) growth. WebJul 9, 2024 · Suspended graphene presents the largest amount of electron–electron interaction. Meanwhile, for graphene on Al 2 O 3, the greatest contribution to scattering mechanisms by far is related to SPP. It must be highlighted that SPP scattering has a strong relaxation ability, yielding a decrease in the carrier energy and, at the same time, not ...
