IN- AND OUT-OF-EQUILIBRIUM SURFACES

English Français

Catalytic reactions at the interface of a surface exposed to a gaseous reactant are often driven far from equilibrium where they manifest nonlinear phenomena such as bistability or oscillations. Remarkably, these phenomena may exist down to the nanoscale under the conditions of field emission microscopy. Phenomena such as oscillating nanopatterns are studied using a multiscale approach combining quantum mechanical calculations with kinetic theory and statistical mechanics.
