Effect of Defects on Thermal Conductivity of Graphene

摘要：

　　Defects could be inevitably generated during the growth or the artificial operation of graphene.The existence of structure defects could be influence to excellent properties of graphene.Non-equilibrium molecular dynamics(NEMD)simulations was used to investigate the thermal conductivity of graphene with single vacancy(SV)and stone-wales(SW)defects.Dependence of temperature showed that thermal conductivity of pristine graphene would decrease with increasing temperature,and graphene with SV and SW defects had weaken temperature dependence than that of pristine graphene.The existence of SV and SW defects could both reduce the thermal conductivity of graphene.However it was indicated that SV defects had more significant effect on thermal conductivity of graphene than SW defects.
