How does a thermionic converter convert heat to electricity?
A Thermionic converter (or generator) converts heat energy directly to electrical energy by utilising thermionic emission effect. In this device, electrons act as the working fluid in place of a vapour (or gas) and electrons are emitted from the surface of the heated metal.
Which is the best essay on the thermionic converter?

What makes an electron emission a thermionic emission?
The emission is a thermionic emission if the energy responsible for it is in the form of heat energy. The electric field has an electric potential energy associated with it. If a charge ‘q’ is present in a potential V, then E =qV.
What is the relationship between emmision and radioactivity?
THERMIONIC EMMISION AND RADIOACTIVITY 1. Thermionic emission is the thermally induced flow of charge carriers from a surface or over a potential-energy barrier. This occurs because the thermal energy given to the carrier overcomes the work function of the material.
