Surfaces and interfaces define the properties of many materials and devices. Applications range from gas-surface interactions exploited in gas sensing and heterogeneous catalysis to electronic properties exploited in microelectronic and optoelectronic devices where interfaces often determine the device operation.
In our laboratory we investigate fundamental surface and interface problems. Well-defined model systems are designed by using advanced in-situ sample preparation techniques that allow us to isolate key components of complex materials and to investigate those properties separately. These model systems are characterized with an array of in house surface science analytical techniques under ultra high vacuum conditions. We supplement these investigations by collaborations with other groups and by synchrotron photoemission and X-ray absorption measurements.
