摘要	We study theoretically the electronic and transport property for an armchair-edge graphene nanoribbon (GNR) with 12 and 11 transversal atomic lines, respectively. The GNR is irradiated under an external longitudinal polarized high-frequency electromagnetic field at low temperatures. Within the framework of linear response theory in the perturbative regime, we examine the joint density of states and the real conductance of the system. It is demonstrated that, by numerical examples, some new photon-assisted intersubband transitions over a certain range of field frequency exist with different selection rules from those of both zigzag-edge GNR and single-walled carbon nanotube. This opto-electron property dependence of armchair-edge GNR on field frequency may be used to detect the high-frequency electromagnetic irradiation.
