Abstract
- Topological models of graphene/CNT composite films are constructed. The films consist of tubes lying irregularly between graphene single layers parallel to them and covalently bound with graphene. The distance between the tubes is measured in graphene hexagons (H1 and H2) between ribs participating in the formation of covalent bonds. It is shown that only films based on zigzag (n, 0)-type tubes with an even number n are energetically stable. The film with the tube (10.0) and arrangement step 6/8 is most stable according to the investigations. It is found that the energy gap is present in the band structure of all studied film models and is in the range of 0.41–0.73 eV. [ABSTRACT FROM AUTHOR]
