The Soret effect in diffusion in crystals
Acta Materialia, 2008Abstract The Soret effect, as it occurs in the diffusion of solutes in crystals, is analyzed using the principle of microscopic reversibility whereby an approach is developed for interpreting and computing Q ∗ , the heat of transport. To compute the transport of energy during the diffusion jump process, and then Q ∗ , the processes of thermal ...

Electromigration and soret effect in cobalt
Solid State Communications, 1966Abstract The present investigation aims to examine whether the electron-ion interaction in hole conductors follows the flow of charge carriers in electromigration experiments, as predicted by theory and observed in several electron conductors. Mass transport of cobalt, a hole conductor, under the influence of a direct current of about 10 4 A

Thermal Diffusion Potentials and the Soret Effect
Nature, 1954WHEN a temperature gradient is applied to a homogeneous solution of an electrolyte, there is a tendency for a concentration gradient to be established (Soret effect). The thermal diffusion potential associated with the temperature gradient should change during the establishment of the Soret equilibrium. For a cell of the type:

Soret effect in periodic forced rayleigh scattering
Optics Communications, 1988Abstract In Forced Rayleigh Scattering of mixtures or suspensions the temperature gratings generate, by Soret effect, concentration gratings that may be very important since they produce both a phase and an amplitude grating superimposed on the principal one.

On the Theory of the Soret Effect in Colloids
2002Movement of colloidal particles can be driven by the inhomogeneous temperature field. In this paper the relation between the phenomenon of the migration of colloidal particles and the characteristics of the protective layer around the grain is established. Two cases of surfacted and ionic colloids are considered.

Observations on Electromigration and the Soret Effect in Tungsten
Journal of Applied Physics, 1965Observations on both electromigration and the Soret effect in tungsten have been recorded using silhouette electron microscopy and electron microscan techniques. The surface structure developed when a tungsten wire is heated by a current density of 3.3×104 A/cm2 depends on whether the current is direct or alternating.
