With the continuous advancement of nanotechnology, nanodevices have becomecrucial components in computing, sensing and energy conversion applications.However, the structures of nanodevices typically possess sub-wavelengthdimensions and separations, which pose significant challenges for understandingenergy transport phenomena in nanodevices. Here, based on a judiciouslydesigned thermal nanodevice, we report the first measurement of near-fieldenergy transport between two coplanar sub-wavelength structures overtemperature bias up to ~190 K. Our experimental results demonstrate aremarkable 20-fold enhancement in heat transfer beyond blackbody radiation. Incontrast with the well-established near-field interactions between twosemi-infinite bodies, the sub-wavelength confinements in nanodevices lead tothe increased polariton scattering and the reduction of supporting modes andtherefore a lower heat flow at a given separation. Our work unveils excitingopportunities for the rational design of nanodevices, particularly for on-chipnear-field energy transport, with important implications for the development ofefficient nanodevices for energy harvesting and thermal management.
