Abstract :
Thermal properties of different metal/graphene interfaces were analyzed by molecular dynamics (MD). Thermal interface conductance of three metal/graphene interfaces, Ni/graphene, Cu/graphene, and Au/graphene, was investigated from 200K to 500K. For Cu/single-layer graphene (SLG) and Ni/SLG interfaces, thermal interface conductance was independent of temperature. Thermal interface conductance was around 537 W/m2K for Ni/SLG interface, and around 465W/m2K for Cu/SLG interface. Thermal interface conductance increased from 236W/m2K to 265 W/m2K from 200K to 500K. It was found to be caused by interactions between graphene and different metal at metal/graphene interface. For thermal management of graphene devices, Ni could be better choices of metal thermal contacts with graphene.
