This year, the Friends of HZB awarded the Ernst Eckhard Koch Prize to Dr. Martin Bluschke (MPI for Solid State Research and TU Berlin) for his outstanding doctoral thesis. The European Innovation Award for Synchrotron Radiation went to a team of four physicists for their work on the FERMI free electron laser at the Elettra synchrotron source in Trieste. The award ceremony took place at this year's HZB user meeting, which had to be held digitally this year.
The award ceremony was well attended with 197 spectators. The chairman of the Friends of HZB, Prof. Dr. Mathias Richter, led the award ceremony on screen and distributed hand-drawn bouquets of flowers as well as the award certificate. The prize committee had read the submitted proposals with great pleasure this year, he reported.
Ernst Eckhard Koch Prize 2020
The Ernst Eckhard Koch Prize went to Dr. Martin Bluschke, Max Planck Institute for Solid State Research in Stuttgart, who completed his doctorate in 2019 at the Technical University of Berlin. The title of his dissertation is: "Resonant x ray scattering studies of collective electronic states in cuprates and nickelates controlled by isovalent chemical substitution and epitaxial integration". Bluschke has been studying so-called collective states in solids at BESSY II, which are related to the phenomenon of superconductivity.
"Mr. Bluschke's dissertation reveals a deep understanding of physics. The numerous results are published to a high standard, which is also reflected by the number of citations," Richter quoted from the prize committee. Bluschke will continue his research at the University of British Columbia in Canada.
Innovation Award Synchrotron Radiation 2020
The Innovation Award Synchrotron Radiation 2020 went to Prof. Dr. Guiseppe Sansone (University of Freiburg), Dr. Luca Giannessi (Istituto Nazionale di Fisica Nucleare, Frascati, Italy), Dr. Carlo Callegari and Prof. Dr. Kevin Prince (Elettra, Trieste, Italy) for their achievements in the development and application of innovative investigation methods exploiting the radiation emitted by seeded free electron lasers at the FERMI free electron laser at Elettra in Trieste. The prize committee acknowledged "this development is of utmost importance for the future" and "concerns ground-braking experiments even on the attosecond scale". The Innovation Award Synchrotron Radiation is endowed with 3000 Euros and is sponsored by SPECS GmbH and BESTEC GmbH.
- 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.
