Abstract
We have prepared three kinds of graphene heat dissipation film as non-continuous single layer single-crystal graphene (NCSG), continuous single layer graphene (CSG) and continuous double layer graphene (CDG). Then graphene was transferred on 2-inches SiO2/Si substrate as heat dissipation film. Temperature field distribution was tested by infrared camera, and thermal conductivity of composite interface of heat dissipation film on SiO2/Si was studied using Fourier’s law. When supply voltage was 10 V, NCSG film made the center temperature dropped by 1 °C, and CSG made the central temperature dropped by 6 °C and the thermal conductivity of CSG on SiO2/Si was increased by 15.7 %. For CSG on SiO2/Si, with the increased of supply voltage, the center temperature drop was increased, but the improvement of thermal conductivity was decreased.
