Seebeck effect   (zā'běk)  Pronunciation Key 
The creation of an electrical potential across points in a metal that are at different temperatures. The effect is caused by the thermal energy of the valence electrons in the warmer part of the metal; the kinetic energy of these electrons, which are very free in metals, allows them to migrate toward the colder part more readily than the colder electrons migrate to the warmer part. The colder part of the metal is therefore more negatively charged than the warmer part, resulting in electric potential. The Seebeck effect is used in thermocouples. It was discovered by the German physicist Thomas Seebeck (1770-1831).

seebeck effect

production of an electromotive force (emf) and consequently an electric current in a loop of material consisting of at least two dissimilar conductors when two junctions are maintained at different temperatures. The conductors are commonly metals, though they need not even be solids. The German physicist Thomas Johann Seebeck discovered (1821) the effect. The Seebeck effect is used to measure temperature with great sensitivity and accuracy (see thermocouple) and to generate electric power for special applications
