Abstract: 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.

Abstract: A semiconductor device includes a MISFET having: a diamond substrate; a drift layer having a first layer with a first density for providing a hopping conduction and a second layer with a second density lower than the first density, and having a δ dope structure; a body layer on the drift layer; a source region in an upper portion of the body layer; a gate insulation film on a surface of the body layer; a gate electrode on a surface of the gate insulation film; a first electrode electrically connected to the source region and a channel region; and a second electrode electrically connected to the diamond substrate. The MISFET flows current in the drift layer in a vertical direction, and the current flows between the first electrode and the second electrode.
