The group of ass. Prof. Jens Uhlig is focused on studying charge carrier and structural dynamics with x-ray methods and optical methods. The group uses large scale facilities as well as a novel in-house developed table top spectroscopy setup. Following the notion that "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.
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.
Methods available in the group:
X-ray absorption fine structure spectroscopy (XAFS)
X-ray emission spectroscopy (XES)
Methods that the groups uses and are available at large scale facilities:
X-ray diffuse scatter (XDS)
X-ray photoelectron spectroscopy (XPS)
