Influence of stretching and compression deformations on the electrical conductive properties of graphene-nanotube composites with an island-type topology

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