Welcome to the Institute for Photon Science and Synchrotron Radiation

The IPS conducts research for and with novel synchrotron analytics and diagnostics (X-ray imaging, spectroscopy, and scattering). Particular focus is placed on in situ, operando, and in vivo techniques for the characterization of technological and biological processes, with emphasis on materials and processes for energy conversion and transport technologies, nano- and information materials, and imaging in the life sciences.

In-situ XRD Characterization of Epitaxial Iron Oxide-based Thin Films grown by Pulsed-Laser Deposition


Hexagonal ferrite oxide materials are promising candidates for high-density, energy-efficient materials for information processing and storage. Using X-ray diffraction (reciprocal-space mapping), we have investigated the structural quality of epitaxial iron-oxide layers grown by pulsed-laser deposition.

Stress evolution during formation of metal/silicon interfaces


In collaboration with the University of Poitiers, we have developed a unique experimental approach combining real-time curvature measurements and synchrotron x-ray reflectivity and diffraction in order to identify the microstructural origins of the stress evolution during sputter deposition of thin films[1].

First high-speed hard X-ray microscopic movies at a free-electron laser


At the European X-ray Free-Electron Laser (EuXFEL) in Schenefeld, Germany a research team have demonstrated for the first time the use of Megahertz (MHz) high-speed X-ray laser microscopy to image the rapid microscopic processes induced by laser heating of water-filled capillaries. Their experiments show how processes taking place at speeds up to a few kilometers per second can be studied, paving the way for 3D microscopic movies of similarly fast phenomena, with important potential industrial applications.

Flux shadowing affects crystal structure in patterned molecular beam epitaxial growth of self-catalyzed GaAs nanowires


Self-catalyzed GaAs nanowires on patterned substrates: Crystal structure and shape are affected by nanowire density due to shadowing effects.
