Graphene monolayer has been grown by chemical vapor deposition on copper and then suspended over a hole. By measuring the laser heating and monitoring the Raman G peak, we obtain room-temperature thermal conductivity and interface conductance of (370 + 650/-320) W/m K and (28 + 16/-9.2) MW/m(2) K for the supported graphene. The thermal conductivity of the suspended graphene exceeds (2500 + 1100/-1050) W/m K near 350 K and becomes (1400 + 500/-480) W/m K at about 500 K.

Chemical-Vapor-Deposited Graphene as a Thermally Conducting Coating

By adopting a simple lumped-elements model, a new method is developed that allows determining the equivalent thermal properties of thermally conductive coatings of nanometric thickness, and it is found that CVD graphene is “thermally equivalent” to a coating material of conductivity keff.
