Graphene nanoribbons as the element base of optical nanodevices


K.R. Asanov – Master Student, Department «Radiotechnique and Electrodynamics», Saratov State University named after N.G. Chernyshevsky O.E. Glukhova – Dr.Sc.

The paper is devoted to the theoretical study of the electronic and optical properties of armchair graphene nanoribbons. As the research tools, we used the software products KVAZAR and MIZAR. One of the problems, which we solved in this paper, was to identify the laws of change in optical properties of graphene nanoribbons with increasing the width. To solve this problem we considered ribbons of different width with step of change equal to 0,246 nm and 4,92 nm. In the result of the calculations, it was revealed that the optical properties of armchair graphene nanoribbons are reduced with increasing the width. The type of nanoribbon electronic conduction is also changed. It was shown that the nanoribbon of 0,492 nm in width has maximum optical conductive at the frequency of 1585 THz (6,55 eV). It is assumed that this nanoribbon can be used at designing optical antennas of UV-range.
