By tailoring the orientation of the graphene ribbons with respect to an array of subwavelength bimetallic electrodes, we achieve a condition in which the plasmonic mode can be efficiently excited by an incident wave polarized perpendicular to the electrode array, while the resulting photothermal voltage can be observed between the outermost electrodes. 2015-07-08 00:00:00 absorption efficiency subwavelength graphene microribbons incident wave photothermal voltage GrapheneWe report electrode array subwavelength bimetallic electrodes area terahertz detector tunable plasmonic resonance plasmonic mode outermost electrodes graphene ribbons
