Under the EU Horizon 2020 Programme for Research and Innovation, Alexander Föhlisch has been awarded an ERC Advanced Grant. The physicists is holding a joint appointment at the Institute for Physics and Astronomy of the University of Potsdam and at the Helmholtz-Zentrum Berlin für Materialien und Energie. He is to receive a total of 2.5 million Euros over a five-year period to support his work on highly selective methods of detection using synchrotron light and X-ray lasers.
The European Research Council (ERC) promotes unconventional, trailblazing research and supports outstanding researchers. Leading scientists at the University of Potsdam are presently carrying out work under six other ERC grants.
The new research project is named “Excited-State Dynamics from Anti-Stokes and Non-Linear Resonant Inelastic X-Ray Scattering” (EDAX). Under this programme, Prof. Föhlisch will study how chemical reaction pathways and phase-transition behaviour can be probed using novel X-ray spectrographic methods. These will serve as a foundation for efficient energy conversion and future energy-efficient information technologies. The University of Potsdam is pushing ahead with cutting-edge research through the EDAX project and consolidating the rising success of the University in EU research programmes.
Alexander Föhlisch studied physics at Eberhard Karls Universität Tübingen and received his German Diplom degree from the University of Hamburg and Master’s degree in physics from the State University of New York at Stony Brook (SUNY). Prior to completing his research and teaching responsibilities for his professorial qualification in Experimental Physics at the University of Hamburg, he conducted his doctoral research at the Advanced Light Source of the Lawrence Berkeley National Laboratory and received his doctoral degree from Uppsala University in Sweden. As a jointly appointed Professor at the University of Potsdam and the Helmholtz-Zentrum Berlin, he is determining the electronic structure and ultrafast dynamics of atomic entities using innovative X-ray methods. Fundamental properties of materials – such as molecular dynamics at boundaries, switching processes in solids and chemical bonding at active centres – can be determined this way.
- A simpler way to inorganic perovskite solar cellsInorganic perovskite solar cells made of CsPbI3 are stable over the long term and achieve good efficiencies. A team led by Prof. Antonio Abate has now analysed surfaces and interfaces of CsPbI3 films, produced under different conditions, at BESSY II. The results show that annealing in ambient air does not have an adverse effect on the optoelectronic properties of the semiconductor film, but actually results in fewer defects. This could further simplify the mass production of inorganic perovskite solar cells.
- Spintronics: A new path to room temperature swirling spin texturesA team at HZB has investigated a new, simple method at BESSY II that can be used to create stable radial magnetic vortices in magnetic thin films.
- BESSY II: How pulsed charging enhances the service time of batteriesAn improved charging protocol might help lithium-ion batteries to last much longer. Charging with a high-frequency pulsed current reduces ageing effects, an international team demonstrated. The study was led by Philipp Adelhelm (HZB and Humboldt University) in collaboration with teams from the Technical University of Berlin and Aalborg University in Denmark. Experiments at the X-ray source BESSY II were particularly revealing.
