Objective
Research objectives and content
It was recently proposed to use a statistical field method in order to describe the structure of I inhomogeneous charged systems. With this approach it has been shown that the Gouy-Chapman theory results from the competition between electrostatic energy and entropy. Moreover, it was possible to extend the Gouy-Chapman theory by starting . from a Landau-Ginzburg like hamiltonian.
In one part of the project these results should be extended to the metal-solution interface. In order to explain the metallic contribution to the interfacial capacity the electronic structure of the surface must be considered. The metal surface, modeled as a jellium, is coupled to the ionic solution, which is treated . according to the primitive model of the electrolyte. Then, it would be very interesting to try a description of i the overall interface on the same footing by using a field theoretic approach. This leads to a treatment of fermions and classicle particles in interaction. From this approach it is expected to gain new insights into the behavior of the electric double layer and to understand the interplay of the different contributions to the interfacial capacity. In the second part of the project the case should be considered in which all these particles are mixed. Then we have to deal with the metal metal-salt mixtures. A large number of experimental results exists for such mixtures. For these systems, which exhibit several phase transitions across the phase diagram, there is no satisfying interpretation, yet. For this part of the project it is proposed to work in close connection with the i experimentalists of the Departement de Physique des Materiaux (Mme. J. Dupuy, Mr. J.F. Jal).
Training content (objective, benefit and expected impact)
The statistical field theory is a completely new method for me. Since this method focus on an intermediate level between a fully microscopic and a macroscopic description and involves mainly analytical calculations, it is a good complement to the computer simulation approach (MD and MC) which I used in my PhD thesis to study electrochemical ion and proton transfer reactions.
