Plasmon dispersion in semimetallic pseudospin-1 α-T<sub>3</sub>-based nanoribbons

POSTER

Abstract

We have calculated the electronic states, Coulomb potential energy, dynamical polarizability and the plasmon discpersion
relations for both intrinsic and extrinsic semimetallic armchair graphene nanoribbons in α-T3 materials. Our obtained results depend on both the parameter α, which is the ratio of the interaction strength and hopping coefficients between the hub and rim-atoms of the hexagonal lattice, and the number of atoms across the nanoribbon. The corresponding results for the dice lattice and graphene are also discussed as limiting cases of our work.
