Abstract
Improved thermionic energy converters are provided by electrodes that include a silicon carbide support structure, a tungsten adhesion layer disposed on the silicon carbide support structure, and an activation layer disposed on the tungsten adhesion layer. The activation layer is a material that lowers the electrode work function, such as BaO, SrO and/or CaO.
