Highly advanced thermal management technology is required for semiconductor devices. This work demonstrated directional heat flow by aligning nanostructures. Heat focusing was demonstrated for the first time in a structure with nano-holes aligned in a radial fashion. This technology develops thermal conduction technology and is expected to contribute to more efficient thermal management in active semiconductor devices.
