Thermophoresis for a single charged colloidal particle
Journal of Physics Condensed Matter 17:14 (2005) S1171-S1176
Abstract:
The microscopic mechanism for thermodiffusion or the Ludwig-Soret effect is investigated for a single charged colloidal particle. For the specific example of a charged permeable membrane, the different forces arising from the interplay between electrostatic interaction and entropy are identified and their magnitudes are calculated in both no-salt and salt-saturated limits. The competition between these forces, which is controlled by the salt density, is shown to decide the direction of motion for the colloids. © 2005 IOP Publishing Ltd.Modelling droplets on superhydrophobic surfaces: equilibrium states and transitions

Luminescence ring formation in quantum wells - A model with Coulomb interaction
Solid State Communications 134:1-2 (2005) 59-62
Abstract:
The appearance of a luminescence ring around a central illumination spot in quantum well structures is now well understood in terms of charge separation between the electron and hole gasses in the quantum well region with the ring appearing at their boundary. We propose a slightly modified model including Coulomb interaction between the electron and hole gas and their image charge. © 2005 Elsevier Ltd.
