I WAS extremely interested in the communication by Messrs. Ratcliffe and Kownacki 1 on the investigation of electron-inertia effects in thermionic tubes. As these writers state, the difficulty in the ...

Typically, if you want to convert solar energy into electrical energy, you use either photovoltaic (PV) cells, or you use the sunlight to create steam to turn a turbine. Both of these methods are well ...

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 ...

(Nanowerk News) In a recent work published in Nature Communications ("Photo-thermionic effect in vertical graphene heterostructures"), the research group led by ICREA Professor at ICFO Frank Koppens ...

IT is well known that the phenomena exhibited by thermionic vacuum tubes begin to alter when the frequency of the potential applied to their electrodes is increased so as to approach the ...
