We are an interdisciplinary team, working on state-of-the-art ultrafast dynamics methods. We have a strong focus on developing a novel, integrated experimental strategies for ultrafast dynamics in condensed matter.
Projects
Time-resolved x-ray crystallography
Understanding the structural dynamics of solids under external perturbation is important since sensitivity to an external perturbation is regarded as either physical and/or chemical properties of crystals. The development of novel experimental methods that cover multiple time scales (from pico- to micro-seconds) allows for selective identification of the specific changes on each time scale and their influence on the materials.
We focus on the development of the state-of-the-art time-resolved x-ray diffraction methods allowing for a better understanding of the dynamical processes in crystalline materials and providing new insights for the design of advanced materials.
- Femtosecond x-ray diffraction
- Stroboscopic time-resolved x-ray diffraction
3D Bragg ptychography
Knowledge of the materials structure and composition at the nanoscale is essential for understanding their physical, chemical, or electronic properties.
We dedicate to Bragg ptychography, a synchrotron based coherent diffraction imaging method we focus on. Bragg ptychography opens access to characterize the crystalline materials with 3D high-resolution imaging methods.
- Biomineral mesoscale structure
- Domain dynamics in ferroelectrics
- Development of data acquisition schemes
Current Researchers
We are always interested in motivated students and postdocs who want to join the group!
