Electronic and energy characteristics of graphene-nanotube quasi-2D films containing point defects

Abstract

Now days, the elemental base of nanoelectronic devices is being developed using low-dimensional materials with unique properties and characteristics. One of the most promising materials in this field is carbon, which is considered by experts as the primary candidate to replace silicon. Among the allotropic modifications of carbon, graphene and carbon nanotubes (CNTs), as well as hybrid materials based on them, are in high demand. The subject of this research is hybrid quasi-2D films formed by AA-stacked bilayer graphene and single-walled carbon nanotubes (SWCNTs) of the armchair (5,5) chirality type. The interaction between bilayer graphene and SWCNTs is mediated by van der Waals forces. The objective of this study is to determine the influence of point defects on the thermodynamic stability and electronic energy characteristics of the hybrid bilayer graphene–SWCNT (5,5) films. The research was conducted using the density functional tight-binding (DFTB) method.
