{wiki=Dufour_effect}
The Dufour effect refers to the phenomenon in thermoelectrics where a temperature gradient induces a diffusion of particles, leading to a variation in concentration. More specifically, when there is a temperature difference within a material, it can cause thermal diffusion of a species (such as ions or molecules) in addition to the normal driven diffusion due to concentration gradients.
