ABSTRACT
The electronic properties of graphene nanoribbon segments in the presence of DNA nucleotides were studied in a series of numerical experiments. Graphene is a monolayer of carbon atoms that are located at the nodes of the hexagonal lattice. The edges of the graphene sheets were hydrogenated to avoid edge effects. The position of the nucleotide above the surface of the graphene sheet can be more optimal with a more successful starting configuration. Despite the similarity of geometry, armchair and zigzag graphene nanoribbons significantly differ in their electronic properties. The material has unique properties, such as high mechanical strength, thermal conductivity, and electrical conductivity, which allowed its application in many areas of electronics. DNA sequencing is an important task, and the search for more convenient, cheaper, faster, and more accurate ways of its solution continues.
