Main group include, thereby forming on the substrate, the organometallic layer by the metal atoms form a bond with the organic molecules, wherein the respective thickness of the metal-organic layer by the duration of the method, by the thickness of the layer of atoms of the oxidizable metal, which on are applied to the respective region of the substrate, and is determined by the number of the organic molecules in the fluid.

For performing the method a substrate having at least on its surface atoms of an oxidizable metal, is provided and exposed to a fluid comprising the organic molecules having at least two functional groups, the elements of VI. Main group include, thereby forming on the substrate, the organometallic layer by the metal atoms form a bond with the organic molecules. With this method produced, preferably structured metal organic layers are used as the metal-insulator or metal-semiconductor structure for the micro- or nano-electronics, as a resist or masking layer in lithography or as a photonic crystal, as well as non-linear optical layer, preferably as an optical waveguide.

In this project, we studied friction and tipsurface interaction by means of newly developed Atomic Force Microscopy based setups in Ulm and Karlsruhe. The methodical focus of the group at the University of Ulm (O. Marti) was on the development and implementation of high-speed scanning force microscopy, allowing the study of microscopic friction as a function of velocity. In the team at the University of Karlsruhe (Th. Schimmel), a novel method was developed and implemented, allowing for studying friction on the nanometer scale as a function of chemical surface modification and functionalization (?Chemical Contrast Imaging?). Furthermore, carbon-based model surfaces were developed for corresponding tribological experiments, and the nucleation and growth of these films was studied, using the newly developed methods. The two types of methods developed within this project are complementary. In close cooperation between the two groups, microscopic mechanism of friction were studied.
