Also produced by charge carrier diffusion, it results from a combination of four emfs, two each named for Thomson and Peltier.
An analogous version was first detected by employing the spin Hall effect, while at temperatures around one-fifth of the Debye temperature, this effect can arise from phonon drag.  Its result is complementary to the Nernst effect, since this effect depends on all dissipative processes that aren't vortex motion, probably because it is governed by a special case of the (*) Onsager relations. Also produced by charge carrier diffusion, it results from a combination of four emfs, two each named for Thomson and Peltier. For 10 points, identify this effect, the operating principle behind thermocouples, in which a temperature gradient generates a voltage.
