Extremely high thermal conductivity anisotropy of double-walled carbon nanotubes

AIP Advances, 2017
Based on molecular dynamics simulations, we reveal that double-walled carbon nanotubes can possess an extremely high anisotropy ratio of radial to axial thermal conductivities. The mechanism is basically the same as that for the high thermal conductivity
