Supported Graphene A Superior Thermal Conductor

Caption: A one-atom thick sheet of graphene (highlighted in the circular window) on top of a silicon dioxide support proves to be an excellent thermal conductor, according to new research published in the journal Science. Although the interaction with the silicon dioxide suppressed the thermal conductivity of graphene compared to its freestanding form, supported graphene still demonstrated much higher heat conducting capability than silicon and copper nanostructures. This finding combined with graphene's superior strength and electron mobility make it a promising candidate for use in next-generation nano-electronic devices.
