Thermal Conductivities

The thermal conductivity of graphene nanoribbons was investigated with nonequilibrium molecular dynamics simulation methods. The results show that the thermal conductivity of nanoribbons lined with zig-zag edges is higher than that with arm-chair edges for the samples with the same width. The phonon density of states is extracted from the molecular dynamics simulation to quantitatively explain the difference between the thermal conductivities of the two kind nanoribbons. The effects of vacancy on the thermal conductivity of nanoribbons are also investigated and it is found the defects on the edge zone play little role than that located in the interior zone of nanoribbons in reducing thermal conductivities.
