  Research: structure and reactions at surfaces

Liquid surfaces:

The goal of our research concerns the understanding of the molecular structure of liquid surfaces and of liquid / liquid interfaces. The experimental tools consist in several electron spectroscopies: MIES (Metastable Induced Electron Spectrscopy), UPS, XPS, EELS. Recently, we have developed ion scattering spectroscopy (ICISS and NICISS) for the application at liquid surfaces. The interpretation of the experimental data is supported by MD (=Molecular Dynamics) computer simulation.

In addition to the above activities which aim at the understanding of the structure at the molecular level we make use of conventional techniques like surface tension measurements. The combination of both approaches has proven very fruitful.

Part of these activities take place within the Graduiertenkolleg "Interaction between Structure and Dynamics within Microstructured Systems" at the universities Dortmund, Bochum and Witten / Herdecke.

Solid surfaces:

In addition to the standard surface analytical methods we use and develop MIES (=Metastable Induced Electron Spectroscopy). We investigate:

  • adsorption of organic molecules on metal surfaces and the properties of self assembled monolayers
  • adsorption of oxygen on metals and the oxydation of metal from the early stages to complete thick oxide layers
  • mechanics of electron emission from surfaces due to the interaction with metastable helium atoms
Part of these activities take place within the Graduiertenkolleg "Dynamics at Solid Surfaces - Adsorption, Reaction, Heterogenous Catalysis" at the universities Bochum, Dortmund and Witten / Herdecke.
