The thermionic current grows with electric field until the negative space charge
near the cathode is eliminated and saturation is achieved. This saturation,
however, is rather relative. A further increase of electric field leads gradually to an

Back emission occurs when an appreciable thermionic current evolves from the
collector; in the cases considered in this report the collector temperature is
sufficiently low compared to the emitter temperature and therefore back emission

(i) Surface area of emitter (ii) Temperature of emitter (iii) Work function of emitter.
If an emitter is heated at different temperatures and corresponding value of
thermionic current is measured then graph between the two will be as shown in
fig.
This is thermionic emission. Richardson-Dushman Equation In thermionic
emission the no. of electrons emitted from an emitter per second (hence
Thermionic current) vary with the temperature of emitter. The relation is given by
a well known ...
