Thermal Diodes Based on Near-Field Radiation
Abstract
The objectives of this work were to demonstrate a thermal rectification phenomenon: non-reciprocal heat transfer between two structures. This effect could be used to maintain the temperature of a device at a lower temperature than its surrounding, unaffected from neighboring hotspots. We proposed to demonstrate experimentally thermal rectification of >40% based on our recent demonstration of near-field heat transfer. Simulation with alumina, silica and platinum coated nano-beams showing ~65% rectification was achieved. The demonstration of thermal rectification >40% between the two nano-membranes was not achieved but potential avenues identified. The current platform, with slight modifications in the deposited layers on the nano-beam surface, is suitable to obtain required separation for near field heat transfer and eventually thermal rectification of >40%.
