Seebeck Physics.|ˈzeɪbɛk|
[The name of Thomas Johann Seebeck (1770–1831), Russian-born German physicist, who discovered the effect (Abhandl. der K. Akad. der Wissensch. zu Berlin: Phys. Klasse (1822–23) 265).]
Seebeck effect, the phenomenon whereby an e.m.f. is generated in a circuit containing junctions between dissimilar metals if these junctions are at different temperatures; the phenomenon of thermoelectricity.
1903Whittaker's Electr. Engineer's Pocket Bk. 99 If a junction between two dissimilar metals be heated or cooled, a flow of electricity will take place across the junction. If a current be passed through such a junction, a change of temperature will be produced. The former phenomenon is known as the Seebeck effect, the latter as the Peltier effect. 1906Sci. Abstr. A. IX. 481 The Thomson-, Peltier-, and Seebeck-effects may be combined in one diagram, and the author does this for the case of iron and silver. 1964S. H. Avner Introd. Physical Metall. i. 6 The total emf in a thermoelectric pyrometer, sometimes called the Seebeck effect, is therefore the algebraic sum of four emf's, two Peltier emf's at the hot and cold junctions and two Thomson emf's along each of the wires. 1973J. G. Tweeddale Materials Technol. I. iv. 97 If an electric circuit is suitably completed a current will flow between the materials (the Seebeck effect). |
