The Seebeck coefficient (also known as thermopower, [1] thermoelectric power, and thermoelectric sensitivity) of a material is a measure of the magnitude of an induced thermoelectric voltage in response to a temperature difference across that material, as induced by the Seebeck effect. [2]
The Peltier effect can be considered as the back-action counterpart to the Seebeck effect (analogous to the back-EMF in magnetic induction): if a simple thermoelectric circuit is closed, then the Seebeck effect will drive a current, which in turn (by the Peltier effect) will always transfer heat from the hot to the cold junction.
The efficiency of a thermoelectric device for electricity generation is given by , defined as =.. The maximum efficiency of a thermoelectric device is typically described in terms of its device figure of merit where the maximum device efficiency is approximately given by [7] = + ¯ + ¯ +, where is the fixed temperature at the hot junction, is the fixed temperature at the surface being cooled ...
A thermoelectric generator (TEG), also called a Seebeck generator, is a solid state device that converts heat (driven by temperature differences) directly into electrical energy through a phenomenon called the Seebeck effect [1] (a form of thermoelectric effect).
Thomas Johann Seebeck (German: [ˈtoːmas ˈjoːhan ˈzeːbɛk]; 9 April 1770 – 10 December 1831) was a German physicist who observed a relationship between heat and magnetism. Danish physicist Hans Christian Ørsted later called this phenomenon the thermoelectric effect .
Seebeck effect imaging (SEI) uses a laser to generate thermal gradients in conductors. The thermal gradients induced generate corresponding electric potential gradients. This correlation of thermal and electric gradients is known as the Seebeck effect. The SEI technique is used to locate electrically floating conductors.
Thomas Johann Seebeck was the first to notice that semiconductors exhibit special feature such that experiment concerning an Seebeck effect emerged with much stronger result when applying semiconductors, in 1821. [38] In 1833, Michael Faraday reported that the resistance of specimens of silver sulfide decreases when they are heated. This is ...
English: Absolute Seebeck coefficient of lead at low temperature, according to Christian, Jan, Pearson, Templeton (1958). 0-7 K : Seebeck is zero since lead is superconducting. 7-20 K: Seebeck measured by thermocouple against superconducting niobium-tin. 20 K and up: Seebeck extrapolated by Christian et al, using previous results of Borelius (1932).
