Thermal effect on anode during field electron emission from cathode
- 28 Downloads
It is demonstrated that, during field electron emission from the cathode, the amount of heat evolved in the anode can differ from the classical value, provided that the translational energy of electrons reaching the anode does not exceed the Fermi energies of electrons in the dissimilar electrode pair. This effect is related to the fact that each electron emitted from the cathode brings the corresponding Fermi energy to the anode, in addition to the energy of the applied field. Therefore, under-or overheating of the anode is possible due to a difference between the Fermi energies.
