Abstract
The influence of structure on the thermal conductivities of single-wall carbon nanotubes (SWCNTs) and graphene nanoribbons (GNRs), is investigated by using molecular dynamics (MD) method. The calculated results demonstrate that, both edge/chirality and width/diameter affect the thermal conductivities of these two low-dimensional carbon materials in nanoscale. However, the effects of structure on the thermal conductivities of SWCNTs and GNRs are different from each other. It is concluded that the influence of structure on the thermal conductivities of SWCNTs and GNRs is not stronger than that on their electric conductivities.
