Electronic states and Coulomb excitations of <i>α</i>-<i>T</i><sub>3</sub> zigzag nanoribbons

POSTER

Abstract

We have examined all possible non-equivalent types of edge terminations for pseoudospin-1 α-T3-based nanoribbons. Our results show that all of their fundamental electronic properties depend significantly on both the hopping parameter α and the particular geometry of their edge. For all non-equivalent edge terminations, we have calculated the electronic wave functions, Coulomb potential, and plasmon dispersion relations. We also report on the dependence of the plasmon dispersion on the electron doping concentration for zigzag edged nanoribbons.
