• TITLE: Next-Nearest-Neighbor Tight-Binding Model of Plasmons in Graphene

  AUTHORS: Vladimir Kadirko, Klaus Ziegler, Eugene Kogan

  KEYWORDS: Graphene; Plasmon; Tight-Binding Model

  JOURNAL NAME: Graphene, Vol.2 No.3, July 17, 2013

  ABSTRACT: In this paper we investigate the influence of the next-nearest-neighbor coupling on the spectrum of plasmon excitations in graphene. The nearest-neighbor tight-binding model was previously considered to calculate the plasmon spectrum in graphene [1]. We extend these results to the next-nearest-neighbor tight-binding model. As in the calculation of the nearest-neighbor model, our approach is based on the numerical calculation of the dielectric function and the loss function. We compare the plasmon spectrum of the two models and discuss the differences in the dispersion.
