Mode Conversion of the Edge Modes in the Graphene Double-Ribbon Bend

Abstract

In this paper, a new kind of graphene double-ribbon bend structure, which can support two edge graphene surface plasmons (EGSPs) modes, is proposed. In this double-ribbon bend, one edge mode can be partly converted into another one. We attribute the mode conversion mechanism to the interference between the two edge plasmonic modes. Based on the finite element method (FEM), we calculate the transmission and loss of EGSPs propagating along this graphene double-ribbon bend in the mid-infrared range under different parameters.

Thermoelectric properties of in-plane 900-bent graphene nanoribbons with nanopores

“…Although a few works have studied the electronic [28][29][30], thermal [31,32], and thermoelectric properties of in-plane bent ribbons [33], their level of efficiency in thermoelectric conversion still needs investigation.…”

“…Due to the strong variation of both electronic and thermal properties of graphene ribbons with specific edge orientation, the thermoelectric performance of bent ribbons could vary significantly compared to their straight counterparts. Although a few works already studied the electronic [29][30][31], thermal [32,33], and thermoelectric properties of in-plane bent ribbons [34], their level of efficiency in thermoelectric conversion still needs investigation.…”
