Abstract
Within the framework of the self--consistent--charge density functional tight-binding method, we study the features of the atomic structure and electrical conductive properties of a hybrid graphene-nanotube film with an island topology under uniaxial stretching and compression. The hybrid film is a composite structure formed by AB-stacked bilayer graphene and horizontally oriented chiral single-walled carbon nanotubes of 1.2 nm in diameter. The regularities of the deformation behavior of the investigated hybrid structure are revealed and the limits of its strength are established. It is shown how the electrical resistance and the current-voltage characteristic of the film change under stretching/compression deformations. Keywords: island-type graphene-nanotube films, uniaxial stretching/compression, resistance, current-voltage characteristic.
