Thiol molecules can build up far more than a monolayer: Substrate-Consuming Metal-Organic Layers (SCMOLs) — •Stefan Walheim 1, Matthias Barczewski1,2, Birgit Riedel1, Jochen Geerk3, Alfred Blaszczyk1, Marcel Mayor1,4, and Thomas Schimmel1,2 — 1Institute for Nanotechnology, Forschungszentrum Karlsruhe, 76021 Karlsruhe (Germany) — 2Institute of Applied Physics, University of Karlsruhe, 76131 Karlsruhe (Germany) — 3Institute for Solid-State Physics, Forschungszentrum Karlsruhe, 76021 Karlsruhe (Germany) — 4Chemistry Department, University of Basel, 4056 Basel (Swizerland)
A novel procedure for the self-assembly of metal-organic layers is described. These layers grow from metal substrates. The organic (thiol)-molecules gradually combine with the metal atoms of the substrate to build up an optically transparent metal-organic solid. The metal atoms are essentially consumed during the growth process. For this reason we call these layers - which can reach thicknesses up to 1 micron - Substrate-Consuming Metal-Organic Layers (SCMOLs). Rutherford Back-Scattering (RBS), Small Angle X-Ray Scattering (SAXS) and Atomic-Force Microscopy (AFM) were applied to gather information about the growth behaviour and the morphology of this nano-structured material. This opens perspectives towards the development of a new type of self-assembled thin solid films with possible applications, e. g. for novel procedures of constructive lithography.
