Welcome to the Division of Synchrotron Radiation Research The Division of Synchrotron Radiation Physics has about 60 employees and covers a wide range of research topics that are interlinked with each other as well as to research groups in Lund, Sweden, and internationally. We perform experimental studies of physical, chemical, structural, and dynamical properties of materials, especially at surfa

Our research concerns the intersection of nanoscience and X-ray science. We use X-rays to investigate nanostructured devices, and we develop nanostructures as X-ray detectors. We have a strong collaboration with the Nanomax beamline at MAX IV, and we also visit other synchrotrons for experiments. Most of the projects also involve colleagues in NanoLund, and we are frequent users of the Lund Nano L

CsPbBr3 metal halide perovskite nanowire X-ray detectors. A) Cross-sectional SEM and B) X-ray image of test pattern with 2 micron lines [Zhang 2022]. C) 3D X-ray microscopy of grains [Dierks 2022]. Metal halide perovskites are most famous for their rapid development in solar cells, but they are also promising materials for X-ray scintillation detectors. We are synthesizing CsPbBr3 nanowire arrays

3D strain simulation and measurement of axially heterostructured nanowire [Hammarberg 2020]. X-ray diffraction can be used to study strain, piezoelectricity and heating in crystalline samples. Modern X-ray optics can reach well below 100 nm focus size, and with coherent phase retrieval methods the spatial resolution can reach around 10 nm. Hard X-rays can penetrate through thick samples, allowing

Imaging of ferroelastic domain dynamics in a CsPbBr3 perovskite nanowire as the temperature is ramped across a phase transition [Marcal 2020]. The Bragg peak and the domain pattern change as the temperature crosses the orthorhombic to tetragonal phase transition at 80C.   3D reconstruction of two ferroelastic domains in a CsPbBr3 nanoparticle [Dzhigaev 2021]. We have recently shown that it is poss

In this project, we have built a phase contrast X-ray tomograph based on a microfocus Cu source. Traditional X-ray imaging is based on absorption contrast, which has poor contrast for small and weakly absorbing samples. Much better contrast can be achieved using phase contrast [Dierks 2020]. The system is based on a microfocus X-ray source with a Cu target, a high-resolution detector and a high-pr

SummaryLight is indisputably at the origin of life on earth, driving all photo-chemical reactions in atmosphere, biological systems, and “man-made" energy related materials. On the atomic scale level, we can describe these photo-chemical reactions, through a multitude of elementary processes occurring on the ultrafast time scale (from sub femtosecond to picosecond) where the initial energy/light h

SummaryTechnical and industrial relevant chemical processes such as catalysis and electrochemistry occur at solid surfaces in complex environments in terms of material composition, pressure, temperature and medium. As a consequence, the atomic scale structure and the environmental composition close to the active material which governs the chemical processes are notoriously difficult to determine.T
