Ubiquitous in the field of electric propulsion, thermionic hollow cathodes are electron sources which utilize thermionic emission from a low work function insert material to achieve large extracted ...

A Spanish-Italian research group has developed a solid-state thermal-to-electric energy converter based on hybrid thermionic-photovoltaics (TIPV) for different applications. It consists of a ...

Electron emission properties underpin the operational efficiency of numerous vacuum electronic devices, making the design and optimisation of cathodes a central theme in materials science. The ...

AMONG many recent books under the general heading of electronics, there has been until now no comprehensive account of the basis of the subject, the thermionic cathode. While it would not be true to ...
