abstract = {An expression for the single-particle thermal diffusion
coefficient of a charged colloidal sphere is derived on the
basis of force balance on the Brownian time scale in
combination with thermodynamics. It is shown that the
single-particle thermal diffusion coefficient is related to
the temperature dependence of the reversible work necessary
to build the colloidal particle, including the core, the
solvation layer, and the electrical double layer. From this
general expression, an explicit expression for the
contribution of the electrical double layer to the
single-particle thermal diffusion coefficient is derived in
terms of the surface charge density of the colloidal sphere,
the electrostatic screening length, and its core radius, to
within the Debye-Hückel approximation. This result is shown
to explain experimental data, for both thin and thick double
layers. In addition, a comparison with other theories is
made.},
