Abstract
New method of thermal energy—to electrical energy conversion in vacuum devices with the metal (W)—dielectric nanofilm (ZrO 2 ) electron source is offered and studied. According to estimates and results of modeling, the energy effectiveness ( χ ) of the proposed method may exceed χ for the known thermionic energy conversion method to 2 - 3 orders of magnitude.
