On September 11, 2020, the Helmholtz-Zentrum Berlin (HZB) and the Leibniz-Institut für Kristallzüchtung (IKZ) signed a cooperation agreement to advance joint research on energy and quantum materials. As part of the cooperation, new types of X-ray optics for synchrotron radiation sources are also being developed.
IKZ and HZB share a long history of joint collaboration: IKZ scientists use the BESSY II radiation source from the HZB on a regular basis for their material science studies. In turn, the crystal growers of the IKZ develop and manufacture components that bring out the special properties of BESSY II.
"We are very pleased that we can strengthen our close cooperation with the cooperation agreement,” says Prof. Bernd Rech, scientific director at the HZB. “At BESSY II we offer a variety of x-ray analytical methods for the analysis of complex material systems. As part of our cooperation, we can use our complementary competencies specifically to jointly develop research areas in energy research and quantum technologies.”
Prof. Thomas Schröder, scientific director at the IKZ, also emphasizes the opportunities that the cooperation between the two research institutions allows: “The IKZ is very interested in initiating joint R&D projects on materials for photovoltaics and power electronics with the scientists of the HZB to maximize our impact in this research area.“ Since Prof. Schröder himself spent part of his career in synchrotron research, there is also a personal affinity towards materials and methods development for large-scale research facilities. “Today I am very happy that IKZ can start new R&D projects with BESSY II in order to support the synchrotron sources with our crystalline materials, for example through active and passive X-ray optics.”
Short description of IKZ:
The Leibniz-Institut für Kristallzüchtung in Berlin-Adlershof is an international competence center for science, technology, service and transfer in the field of crystalline materials. The research and development spectrum ranges from basic and applied research to pre-industrial research tasks. The IKZ develops innovations in crystalline materials through its expertise in plant engineering, numerical simulation and crystal growth to achieve crystalline materials of the highest quality with tailored properties. The unique selling point of the institute is the research on volume crystals. This work is accompanied by research and development on nanostructures and thin films as well as strong theoretical and experimental research into materials.
- 3D magnetic field experiment at BESSY II takes spintronics a step further(Fe0.63Ni0.3Pd0.07)3P or FNPP is a magnetic material that exhibits complex magnetic structures even at room temperature. This makes the material of interest for spintronics, a field that could enable data processing with significantly lower energy consumption. One potential application is novel magnetic memory devices. However, generating and modifying the desired structures in a controlled manner remains a challenge to date. A new study led by HZB has now taken a step forward in this regard. They demonstrated at the worldwide unique VEKMAG-Station at BESSY II, that a tiny external B-field in the plane of the magnetic patterns is sufficient to change them.
- Thin nickel films boost green hydrogen productionUltra-thin nickel oxide coatings can significantly improve the performance of anion exchange membrane (AEM) water electrolysers, a promising technology for producing green hydrogen. This was demonstrated by a team led by HZB scientist Dr. Michelle Browne. The results show that a nickel oxide film only 10 nanometres thick outperformed conventional nickel oxide powder electrodes while using less than 1% of the catalyst material. The study is published in the Journal of Materials Chemistry A,
- Confirmed figures for the first time: Investments in BESSY are worthwhile for Berlin and GermanyAn impact analysis by DIW Econ demonstrates the scientific and economic value of BESSY II. Every euro invested yields three euros for Germany and as much as ten euros for the State of Berlin. Furthermore, the study provides an economic forecast for the construction of BESSY III.
The impact analysis was presented on 3 September 2026 to Dr Henry Marx, State Secretary for Science and Research in the Berlin Senate. He supports the investment and is a strong advocate for BESSY III.
