A combined photoemission and LEED study of SnPc/Ag (111) — •Stephan Jauernik, Max Gurgel, Petra Hein, and Michael Bauer — Institut für Experimentelle und Angewandte Physik, Christian-Albrechts-Universität zu Kiel

Recently, the adsorption of tin-phthalocyanine (SnPc) on Ag(111) has attracted considerable interest due to peculiarities in the adsorbate-substrate interaction [1] and switching capabilities reported for the adsorbed SnPc [2]. In a combined Low Energy Electron Diffraction (LEED) and Photoemission/Two-Photon Photoemission (PES/2PPE) study of SnPc/Ag(111) we address in this work the correlation of the structural and the electronic properties of this model system in the sub-monolayer coverage regime. The study focuses on the transition regime from a gas - like phase at coverages <0.90 monolayers (ML) to an incommensurate phase observed for coverages between 0.90 ML and 1.0 ML. The photoemission data reveal distinct changes in the occupied as well as unoccupied electronic structure of this model-type organic adsorption system as the coverage increases. The experimental results are discussed under consideration of past LEED, STM and STS studies [1,2].
