| Abstract | We have used classical molecular dynamics based on the Brenner potential to calculate the thermal conductivity of rectangular graphene nanoribbons up to 30 nm long. We have employed the Debye model to make the quantum correction of the classical molecular dynamics temperature. The calculated thermal conductivity is on the similar order of magnitude of the experimentally measured value for graphene. The edge chirality dependence of thermal conductivity shows that nanoribbons with zigzag long edges have larger thermal conductivity than that of nanoribbons with armchair edges. Our investigation of the size dependence of the thermal conductivity indicates that the calculated value is limited by the finite length of nanoribbons. |
