Abstract
A thermoradiative device for generating power includes a thermoradiative element having a top surface and a bottom surface, wherein the thermoradiative element is a semiconductor material having a bandgap energy Eg. The device includes a thermal conductive element having a first surface and a second surface, wherein the first surface is arranged to face the bottom surface of the thermoradiative element, and the first surface is a structured surface having a periodic structure, wherein the structured surface is separated from the bottom surface with a distance d to establish near-field resonance between the bottom surface and the structured surface. The device further includes supporters configured to bond the thermoradiative element and the thermal conductive element.
