Electrical and Optical Properties of Nitrogen- Doped Armchair Graphene Nanoribbons: A First-principle Study

Recent researches and investigations showed that graphene nanoribbons are versatile choices forelectronic and optoelectronic devices, due to their significant electronic and optical properties. In this paper wediscuss armchair graphene nanoribbons employing density functional theory method as a first- principle study. We calculate electronic and optical properties of intrinsic and nitrogen- doped armchair graphene nanoribbons. We observe that doping has a significant impress on electronic and optical properties of different families of the armchair graphene nanoribbons. We show that nitrogen- doping makes different changes such as red- shift in optical absorption which is necessary in optoelectronic devices. In addition, doping plays an important role in graphene- plasmornic devices.
