ABSTRACT

The purpose of this paper is to study the laws of the influence of the topology of the 2D composite material of carbon nanotube (CNT)-graphene on their optical properties. All insilico studies are carried out in the MIZAR software package using the SCC DFTB2 method. As a 2D-composite, we consider a layer of parallel single-walled CNTs (SWCNT), located at the same distance from each other, enclosed between two monolayers of graphene and connected with them by covalent bonds. In the construction of topological models of composites acrylic SWCNTs of the zigzag type with a diameter of ~ 0.9 nm รท 1.4 nm, most often synthesized in macroscopic volumes, participated. Optical properties were studied for topological models of composites with tubes of the form (12,0), (14,0), (16,0) and (18,0), the distance between them being 9-13 hexagons. The subject of scientific interest in the work was the study of the interaction of electromagnetic radiation with electrons in the 2D composite of CNT graphene by obtaining calculated data on the main optical characteristics of the composite material - reflection, absorption and transmission coefficients.
