Uhlig Group

General activity

The group of ass. prof. Jens Uhlig is focused on studying charge carrier dynamics and structural dynamics with x-ray - and optical methods. The group uses large scale facilities as well as develops novel in-house table top spectroscopy setup. Following the notion "seeing is believing" we use the element selectivity of hard and tender x-radiation to localize electronic and structural changes in complex molecular structures with the time-resolution of ultrafast lasers. We can thus follow light induced excitation and optimize charge transfer pathways.

Our own development is a pulsed table top x-ray source based on a water target combined with a novel energy dispersive microcalorimetric detection system. With this system we can study sub-picosecond dynamics using hard and tender x-rays in a table top system.

Methods available in the group:

X-ray absorption fine structure spectroscopy (XAS) 
X-ray emission spectroscopy (XES)
Transient optical absorption spectroscopy (TAS)


Methods that the groups uses and that are available at large scale facilities:
X-ray diffuse scatter (XDS)
X-ray photoelectron spectroscopy (XPS)
