Research topics

Surface spectroscopy serves to get information about the chemical nature of sample surfaces or surface near regions. For those a spectrometer working under ultra-high vacuum conditions is used. The X-ray photoelectron spectrometer allows analyzing the elemental surface composition quantitatively. Different binding states of the detected elements may be distinguished. Angle resolved photoelectron spectroscopy is a non-destructive method to investigate the distribution of elements or functional groups in the depth of the sample surface. Beside the spectroscopic information the X-ray photoelectron spectrometer provides the possibility to study the lateral distribution of elements on a sample surface on a micrometer scale.

The knowledge of the chemical surface composition and the kind of functional surface groups is the fundament to evaluate surface reactivity and apply chemical and physico-chemical methods to modify the solid surface.

Equipment

Photoelectron spectrometer AXIS ULTRA (Kratos Analytical, UK) equipped with a X-ray source for non-monochromatic  Mg K alpha X-ray irradiation and monochromized X-ray sources for A1 K alpha and Ag L alpha X-ray irradiation.
Samples on stages and under investigation can be heated (up to 600°C) or cooled (up to -195°C).
Further features are small-spot XPS analysis (smallest field of view 27 µm), imaging XPS (lateral resolution ca. 10 µm)
