The experimental research group led by Udo Weimar adresses the fabrication and characterization of metal oxide layers specifically with respect to chemical sensors. Current research tpics are the analysis and modification of nanoscale, crystalline oxides such as zinc oxide, tungsten oxide, indium oxide, etc. In order to improve the properties of the sensors, a targeted preparation of nanoscale, crystalline layers is important. For their investigation, integrated techniques are the state of the art. In order to model the effects it will be necessary to consider individual objects (e.g., isolated nano wires) including their contacts. This requires e.g. the precise deposition of contact materials such as platinum directly on the nanoscale objects on adequate substrates. For the preparation of substrates the research group cooperates with the Kern/Fleischer group; with respect to spectroscopic issues at surfaces with the Chassé group and concerning morphological characterization with the Kölle/Kleiner research groups.
