HZB Researcher on the Board of Directors of the Materials Research Society
Catherine Dubourdieu is head of the IFOX Institute at HZB and was elected now into the board of directors of the MRS.
In September 2019, Prof. Dr. Catherine Dubourdieu was elected into the Board of Directors of the Materials Research Society (MRS). The MRS is one of the largest scientific associations and has almost 14000 members from various areas of the natural sciences and engineering.
Catherine Dubourdieu heads the HZB-Institute IFOX (Functional Oxides for Energy Efficient Information Technology) and holds a professorship at the Freie Universität Berlin. She investigates the growth and properties of functional oxides and semiconductor materials with the aim of developing energy-efficient devices for information technology, that can be integrated on silicon chips. Over the past 15 years, the physicist has also established numerous collaborations with industry and holds 10 patents. She has already published over 140 articles in peer-review journals and has an excellent international network.
In the Materials Research Society Catherine Dubourdieu has been active for over 20 years, also in responsible functions. As of 2020, Catherine Dubourdieu will be a member of the MRS Board of Directors to support the global materials research community and provide a framework for the various disciplines to collaborate.
The MRS's mission is to advance international interdisciplinary materials research and technology for the benefit of the human society. It was founded in 1973 and today has around 14000 members from various areas of the natural sciences and engineering. The governance of the Society is the responsibility of the Board of Directors, composed of 6 officers and 18 directors, 15 of whom are elected by the membership. One third of the Board is renewed each year. Catherine Dubourdieu will serve in this position over the next three years.
- Superconducting TES array X-ray spectrometer goes into operation at BESSY IIThe TES-Spectrometer was developed within a collaboration between the HZB, the MPI-CEC (Mühlheim-an-der-Ruhr, Germany) and the NIST (Boulder CO, USA) and is now in operation at BESSY II, as the only TES-Spectrometer at a synchrotron source in Europe. The photon detection efficiency of the new instrument exceeds that of wavelength-dispersive X-ray emission spectrometers by a factor of 100 to 1000. It will be used to investigate the electronic properties of atomically thin layers, nanostructures and highly diluted atomic and molecular samples. The team is looking forward to receiving exciting research proposals from the user community.
- X-ray analysis reveals overpainted fascist symbolsErich Mercker was a successful painter during the Nazi era and in the years that followed. After 1945, he covered up Nazi symbols in at least one of his paintings. With an interdisciplinary team, physicist Dr Ioanna Mantouvalou reports on this study in the Nature Journal Heritage Science.
- Magnon momentum microscopy: A new window into nanoscale spin-wavesAn international team lead by the Max Born Institute has developed a new type of momentum microscopy to image magnons — the quanta of collectively excited spins — directly in two-dimensional reciprocal space using soft X-rays. Measurements have taken place at BESSY II and PETRA III, first author ist the HZB physicist Steffen Wittrock. Owing to its remarkable sensitivity, simplicity, and access to nanometer-scale wavelengths, this novel technique establishes a powerful and versatile platform for exploring nonlinear magnon interactions, which are promising for future computing schemes.
