By employing material such as silicon (Si), germanium (Ge) and gallium arsenide (GaAs), electronics manufacturers have been able to replace traditional thermionic devices that made electronic items heavy and non-portable.
Since the relation [W.sub.s] < [W.sub.Me] is satisfied when the metal is in contact with semiconductor, current of thermionic emission from semiconductor surface is greater than from metal surface.
However, the proposed LT-SWH system has no corrosion and freezing problems during winter, and it has low heat loss at night due to the peculiarity of thermionic diode of LT.
Second, thermionic emission has a time delay which is not conducive to the improvement of the temporal resolution.
The thermionic field emission theory based model for metal (M)-semiconductor (S)-metal (M) system with two corresponding Schottky barriers at M/S interface was used to approximate the obtained nonlinear IVCs for [Bi.sub.2][S.sub.3] nanowires (detailed process in [21, 22]).
These electrons in EL arise because of the phenomenon of their thermionic emission from the surface of a metal cathode heated by direct (alternating) heating current to high temperature (about (800-3000)[degrees]C) [2, 5].
No matter what your scientific persuasion, when you consider that less than a single human lifespan ago, the first digital computers were developed and utilized the physics of thermionic electron flows through a vacuum, you must admit a lot has changed in a very short amount of time.
(1.1) has been subject of many studies in the literature such as the theory of stellar structure, thermionic currents and isothermal gas spheres [11].
The conduction mechanisms initially considered for modeling these gate tunneling currents were Ohmic Conduction (OC), Thermionic Emission (TE), Space-Charge Limited Current (SCLC), Trap-Assisted Tunneling (TAT), Poole-Frenkel (PF), and Fowler-Nordheim (FN).
Following the previous investigation [8, 10], the I-V characteristics of the forward bias current were analyzed in accordance with the Richardson-Schottky model that assumes direct current electrical conduction through electric field assisted thermionic emission.
