Abstract

We measured the thermal resistances of the Au/graphene/SiO2, Au/Ti/graphene/SiO2, and Au/Cr/graphene/SiO2 structures. The thermal resistances of the three structures were found to be significantly higher than those of the corresponding graphene-free structures, indicating that even monolayer graphene can greatly increase the thermal boundary resistance at metal/SiO2 interfaces. Furthermore, the thermal resistance of the Au/Cr/graphene/SiO2 structure is unexpectedly significantly higher than those of the other two structures, indicating that the diffusion mismatch model (DMM) fails to predict the thermal boundary resistance at metal/graphene interfaces. The poly(methyl methacrylate) (PMMA) residue contamination layer on the graphene surface may play an important role in increasing the thermal resistances of metal/graphene/SiO2 structures. Also, transition metal/graphene and transition metal/PMMA interactions may also affect the thermal boundary resistance.
