▎ 摘　　要

Composite structures of graphene and carbon nanotubes (CNTs) have attracted great interest due to their expected distinguished properties. Here we have investigated the mechanical and electronic properties of new nanostructures based on CNT-graphene covalent-bonded compounds. [GRAPHICS] The process of the formation of the graphene-nanotube compound. Left: single graphene and nanotube (border atoms of graphene are highlighted). Right: carbon nanotube-graphene composite.
