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 .
The Seebeck and Peltier effects are different manifestations of the same physical process; textbooks may refer to this process as the Peltier–Seebeck effect (the separation derives from the independent discoveries by French physicist Jean Charles Athanase Peltier and Baltic German physicist Thomas Johann Seebeck). The Thomson effect is an ...
In 1821, Thomas Johann Seebeck discovered that a thermal gradient formed between two different conductors can produce electricity. [5] [6] At the heart of the thermoelectric effect is that a temperature gradient in a conducting material results in heat flow; this results in the diffusion of charge carriers. The flow of charge carriers between ...
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]
Thomas Johann Seebeck (1780–1831) discovered the thermoelectric effect in 1821. The symmetrical Peltier effect ( Jean Charles Athanse Peltier , 1785–1845) uses an electric current to produce temperature differences.
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 ...

German scientist Thomas Johann Seebeck discovered thermoelectricity. 1825: English physicist William Sturgeon developed the first electromagnet. 1827: German physicist Georg Ohm introduced the concept of electrical resistance. 1831: English physicist Michael Faraday published the law of induction (Joseph Henry developed the same law ...
