Abstract

See full text

A thermionic power generator includes an emitter generating thermions and a collector collecting the thermions. The emitter includes an emitter substrate having an electric conductivity, a low resistance layer stacked to the emitter substrate and made of an n-type diamond semiconductor that includes phosphorus as a donor, and an electron emission layer stacked to the low resistance layer and made of an n-type diamond semiconductor that includes nitrogen as a donor. The collector includes a collector substrate having an electric conductivity and is disposed opposite to the emitter via a clearance. The electron emission layer has a thickness equal to or less than 40 nm.
