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

Where these values of ; exceed the theoretical value of the thermionic current
density, jR, given by the Richardson equation, jR - APexpi-ye/kgT), Zhu and
colleagues [1992] have assumed that this extra current is carried by positive ions;
A is ...

According to this relation I -± Current density (J) = o = AT2 e kj where I is
thermionic current, S is surface area, 0 is work function, T is absolute temperature
of emitting surface and A is thermionic constant which depends only on the
nature of ...

5. Richardson-Dushman equation for thermionic emission. This equation gives
relation between current density (J); and the absolute temperature of the emitting
surface. J = I/S = AT^-f^7 where I = Thermionic current T = Absolute temperature ...

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
can ...

(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 ...

B) Above Vth2, when the tunnel barriers pass below EFS, the filtering action of
the Fermi-Dirac statistics vanishes and non-confined transmission states above
the well start to drive a significant amount of thermionic current (5). As observed
in ...

A transistor already dominated by the thermionic current below threshold, that is,
with LC being too large, will have characteristics very similar to a MOSFET but
with a shifted threshold voltage, that is, Vth = Vth2 (e.g., transistor with LC = 8 nm
