Seebeck effect

See·beck effect

 (zā′bĕk)
n.
The creation of an electrical potential across points in a metal that are at different temperatures, caused by the tendency of valence electrons in the warmer part of the metal to migrate toward the colder part because of their thermal energy. The Seebeck effect is exploited in the design of thermocouples.

[After Thomas Johann Seebeck (1770-1831), Estonian-born German physicist.]

Seebeck effect

(ˈsiːbɛk; German ˈzeːbɛk)
n
(General Physics) the phenomenon in which a current is produced in a circuit containing two or more different metals when the junctions between the metals are maintained at different temperatures. Also called: thermoelectric effect Compare Peltier effect
[C19: named after Thomas Seebeck (1770–1831), German physicist]

For example, hot-and-cold redox batteries and devices based on the Seebeck effect are not possible to simply bury them inside a heat source and exploit them.
Here, a continuous voltage arises due to the Seebeck effect, and if the circuit is closed on an external load ([R.sub.e] in the figure), an electric current flows.
To overcome the trade-off between current density and the skyrmion velocities, the solution based on the spin Seebeck effect [13, 14] and spin wave [15, 16] (SW) are proposed recent years.
This power generation capability stems from the Seebeck effect, which was discovered originally by Alessandro Volta in 1787 and rediscovered independently by Thomas Johann Seebeck in 1821 [1].
At present, thermoelectric power generation modules based on bulk [Bi.sub.2][Te.sub.3]-based materials are more used for microenvironmental cooling and local precise temperature control using the Peltier effect (the inverse effect of the Seebeck effect) [IO, Il].
A first order mathematical expression of the Seebeck effect for each line is the following:
The heat absorption into the TEC cold side, [[??].sub.Cold], may be formed using the Seebeck effect, n[alpha]I([T.sub.hot]+[T.sub.cold]).
Harvesting Thermal Energy: Thermoelectric energy harvesters work on the basis of the Seebeck effect. Here a voltage is produced depending on the temperature difference at the junction of two dissimilar conductors.
Thermoelectric conversion is based on the Seebeck effect, which causes electrical energy to be generated when a temperature gradient is applied to thermoelectric elements.
The Seebeck effect and Seebeck coefficients describe the relationship between voltage and temperature in conductors.
Furthermore, the combination of the thermoelectric effect termed the "Anomalous Nernst Effect,"(4) appearing due to the ferromagnetic properties added to the cobalt alloys and the spin Seebeck effect, have improved the thermoelectric conversion efficiency by more than 10 times.
