Graphene Thermal Conductivity Dependence on Using Non-Equilibrium Molecular Dynamics Simulations

Author(s): Zhongwei Q

Due to the increasing thermal management has become a serious problems in electric devices, especially in nanodevices.Graphene has been considered as a potential heat transfer material. However, the thermal conductivity in graphene demonstrates the discrepancy between the simulatedvalue and the experimental results. We computed the thermal conductivity of graphene (from length of 21.84 nm to 43.78 nm) on nanoscacle size using NEMD method. The results demonstrate obvious edge type (zigzag edge and armchair edge) and nanostructure size dependence of thermal conductivity. With graphene length << MFP (Phonon mean free path), thermal conductivity increase with the length increasing and is strongly limited by the sample size owing to a dominant boundary scattering. Besides, the thermal conductivity of graphene with zigzag edge is larger than the armchair edge, which is because of the higher phonon group velocities.
