摘要：
Non-equilibrium molecular dynamics (NEMD) simulation method is used to investigate the in-plane thermal conductivity of graphene with different structures. The simulation results demonstrate that, as the length of simulated region increasing, the in-plane thermal conductivity of graphene will become larger. Through investigating the influence of width and edge structure on the in-plane thermal conductivity of graphene, it is also found that the thermal conductivity of wider simulated sample is higher than that of the narrower, and with similar length, the in-plane thermal conductivity of armchair graphene is a little higher than that of zigzag one. The effect of temperature on the thermal conductivity of graphene is also studied in this work.
