We conduct fundamental and applied investigations in the physics and chemistry of surfaces, including their modification by atoms, molecules and solid thin films. Our experimental techniques allow us to reveal atomic arrangement at surface, follow growth of thin films and observe forming and breaking of chemical bonds (reaction dynamics). By utilizing circularly polarized X-rays we can also shed light on the magnetic properties of thin films, sandwiches of magnetic and non-magnetic materials, as well as ensembles of nano particles. Our research is highly relevant for heterogeneous catalysis, thin film technology, nanotechnology, spintronics and molecular electronics.

Analysis techniques include soft X-ray Absorption Spectroscopy (XAS), Low-Energy Electron Diffraction (LEED), Photoelectron Spectroscopy (PES), X-ray Magnetic Circular Dichroism (XMCD) and X-ray reflectivity measurements.

Our research is focused, in particular, on the following topics (among others):

• Molecular interactions with metal and alloy surfaces
• Dilute magnetic oxides and semiconductors
• Magnetic properties of metal and semiconductor nanoparticles
• Organic semiconducting thin film molecular magnets
• Graphitic nano sheets and nano tubes
• Self-organization of molecules and nano particles on surfaces
• Synthesis and characterization of novel functional oxides
• Molecular networks
• Complex molecules (DNA, etc.)
• Molecular electrodes for solar cell applications
• Functional surfaces for medical applications
• Organic-ferromagnetic hybrid interfaces for spintronics
