Optical Properties of Low-Dimensional Systems: Methods of Theoretical Study of 2d Materials

Abstract

Heterostructures based on graphene and two-dimensional films of nanostructured, ferromagnetic, transition metal oxides are promising for the development of new multifunctional materials for memory cells, quantum computer elements, Li-battery anodes, (photo) catalysts, supercapacitors, transistors, sensor materials, solar panels, fuel cells, electrochromic devices. A large volume of publications devoted to graphene and heterostructures based on it is and mainly their synthesis processes of hybrid structures. The methods of theoretical investigation of the optical properties of two-dimensional film materials, despite their diversity, require improvement. Consequently, the article presents methods of theoretical investigation of the optical properties of two-dimensional hybrid film structures in combination with ab-initio method.
