Abstract

We present an experimental study of cross-plane thermal conductance in metal-graphene-oxide stacks employing time-domain thermoreflectance (TDTR) measurements on Al/m/graphene/SiO2structures with monolayer graphene for varying adhesion metals m. Thermal conductance G in the range of 15-60 MWm2K1are found across several metals - a two-to-fourfold decrease over Al/m/SiO2reference values, charted against metal Debye temperature over a 274-630 K range, as well as electronic work function. The results of this study help with a better understanding of the roles of electron and phonon transport in thermal conduction across graphene-metal interfaces, revealing potential trade-offs between electrical contact resistance and heat management in graphene devices.
