All are welcome


We experience soft matter interfaces in daily life, but they play also an important role in many industrial processes. In this seminar I want to consider three quite different types of soft matter interfaces and how to investigate them with ion scattering and electron spectroscopy. Ion scattering allows measuring concentration depth profiles with a depth resolution of a few Å close to the surface. Electron spectroscopy allows measuring the chemical composition and electronic structure of the surface near region. Choosing the radiation – X-rays (XPS), UV light (UPS) or metastable He atoms (MIES) – determines which depth is probed. MIES allows investigating exclusively the outermost layer while XPS probes also the deeper layers.

The seminar will cover interface in organic based photovoltaics, liquid interfaces and ligand protected metal clusters on surfaces. Each of the three subjects has its own area of interest. Interfaces play an important role for the functioning of organic based photovoltaics. Liquid interfaces play an important role in reactions in the atmosphere. Ligand protected clusters on surfaces can be used as photocatalysts for water splitting.
