Intramolecular resolved STM-data of Biphenyldithiol-molecules on Au(111) — •Michael Lochner, Michael Waelsch und Rene Matzdorf — Universität Kassel, Fachbereich Naturwissenschaften,

We have investegated submonolayers of the organic molecule Biphenyldithiol on an Au(111)-surface with STM-methods. The molecules are physisorbed on the surface. Three types of typical structures have been found, which are dependent on the local coverage. We show intramolecular resolved data of molecules in all three structures. Additionally, workfunction-maps were measured by lock-in-technique. In some cases they show even more details of the molecule structure than usual STM-topographies.
