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 idea "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.
The current research focus lays on intra and inter-structure charge transfer reactions. These can occure in Molecules or in nano-dimensioned light absorbing particles such as nanowires.
Current directions are:
Photo-electro-catalysis transfer 
Molecular charge transfer
As this is a challenging topic the groups also works on creating methods and facilities to enable these measurements:
We developed a pulsed table top x-ray source based on a water target combined with a novel energy dispersive microcalorimetric detection system. For more information please see this project page.
The group is developing data Analysis software for Modelling of development spectroscopy, such as transient spectroscopy. For more information please see this project page .
Methods available in the group (inhouse):
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)
