At first glance, the thermionic converter in Thermo Electron's lab looked like a
huge inverted test tube. As I tried to fathom the jumble of wires and tubes inside
the glass bell jar, Dr. Peter Oettinger, who heads a small research group here, ...

A Thermionic Emission If we heat any material to a high-enough temperature, we
can give the electrons sufficient energy to overcome the natural barrier that
prevents them from leaking out from the surface. This barrier is termed the work ...

Thus thermionic emission is defined as "the phenomenon in which free electrons
are emitted from a metallic surface, by the absorption of heat energy supplied to
them". The electrons thus emitted are called thermions. The free electrons of the ...

Electronics (fundamentals And Applications)
This gives four different modes of electron emission from a metal: (1) thermionic
emission, (2) photoelectric emission, (3) secondary emission, and (4) field
emission. Thermionic emission occurs when the additional energy is supplied to
the ...
