Tackling Molecule-Surface Interactions Using Embedding Methods
Speaker:Florian Libisch (Vienna University of Technology)
Abstract:Quantum mechanical embedding methods allow for the theoretical description of problems that cannot be tackled with one single ab-initio method. One prominent example is the interaction of a gas molecule with a metal surface. Embedding methods combine the advantages of different methods: a system of interest is partitioned into different parts (e.g. the approaching molecule interacting with a small surface cluster, and the remainder of the surface), which are each described by a suitable method. Their interaction is mediated by a global embedding potential. We present different approaches to determine this embedding potential, and discuss two applications: the dissociation of oxygen molecules by an aluminum surface, and the hot-electron mediated dissociation of hydrogen on a gold surface. For both cases we compare to experimental results.
