Thermal properties of graphene and few-layer graphene: applications in electronics

The authors review thermal properties of graphene and few-layer graphene (FLG), and discuss applications of these materials in thermal management of advanced electronics. The intrinsic thermal conductivity of graphene - among the highest of known materials - is dominated by phonons near the room temperature. The examples of thermal management applications include the FLG heat spreaders integrated near the heat generating areas of the high-power density transistors. It has been demonstrated that FLG heat spreaders can lower the hot-spot temperature during device operation, resulting in improved performance and reliability of the devices.
