Equipe: Chemical Physics and Dynamics of Surfaces

Team Permanent members: Marie-Claude Fauré, Michel Goldmann   The formation of metal–organic interface is an open question in material science with applications from colloïds (microcatalysis) to thin layers (microelectronics). In the radiolysis method, the irradiation...

Team Permanent members: Marie-Claude Fauré, Michel Goldmann Forming a Langmuir film by deposing a solution on the surface of the water subphase is the standard procedure which has been shown to be effective with most...

Team Permanent members: Marie-Claude Fauré, Michel Goldmann PhD Student: Pedro Silva The physics behind Langmuir films seemed understood since the publication of the generic phase diagram describing all the phases observed with “simple” molecules. However,...

Team Permanent members: Emmanuelle Lacaze, Sébastien Royer PhD Students: Lamia Essaoui, Caterina Tosarelli, Xintao Zheng Liquid crystal topological defects are among condensed matter topological defects the easiest to control for a deep study of defect...

Team Permanent members: Emmanuelle Lacaze, Sébastien Royer, Michel Goldmann Liquid crystal topological defects are among condensed matter topological defects the easiest to control for a deep study of defect structure and properties. We know now...

Team Permanent member: Olivier Pluchery Molecules are self-assembled into monolayers on silicon surfaces with an extreme control so that we can avoid any oxidation of silicon, even at room pressure. We have especially studied...

Team Permanent member: Olivier Pluchery   Gold nanoparticles can be viewed as extra-small electrodes and help understand how electronic currents can be controlled at the smallest scale at complex interfaces. The unrivalled advantage of...

Directional solidification in thin samples of a eutectic alloy CBr4-C2Cl6. The solid is two-phase, composed of two different crystalline phases α and β. Diffusive dynamics are at the origin of the periodic alternation of...

  “Faceton”, or faceted solitary wave, in directional solidification in a thin sample of a mesomorphic molecule (denoted CCH4) exhibiting a nematic-smectic B transition. Smectic B is a “plastic crystal” phase with a lamellar...

Directional solidification in “thick” samples (typically 0.5 mm thick) of CBr4-C2Cl6 and succinonitrile-camphor alloys of concentrations inside the eutectic plateau. The solid is two-phased, composed of two different crystalline phases α and β. Diffusive...
