Prof. Dr. Catherine Dubourdieu heads the Institute “Functional Oxides for Energy-Efficient Information Technology” at HZB and is Professor at the Physical and Theoretical Chemistry division at Freie Universität Berlin. The physicist and materials scientist specialises in nanometre-sized functional oxides and their applications in information technologies. She has now been awarded a prestigious ERC Advanced Grant for her research project “LUCIOLE”, which aims at combining ferroelectric polar textures with conventional silicon technologies.

With its ERC Advanced Grant format, the European Research Council enables outstanding scientists to conduct pioneering and groundbreaking high-risk research. An ERC Advanced Grant is considered one of the highest awards for experienced researchers.

The project LUCIOLE focuses on ferroelectric nanometer-size oxides, which can host exotic polar textures such as vortices or skyrmions. With a wealth of potential emergent properties, whirling topological polar nanodomains could lead to novel devices, for example ultra-compact memories that store more than a terabyte per square inch. “We want to pave the way to future low power nanoelectronics based on topological defects” says Catherine Dubourdieu.

Monolithically integrated polar textures on silicon will be created and investigated on a nanoscale with state-of-the-art microscopy and spectroscopy techniques. These engineered polarization patterns will be embedded into ultra-scaled devices to study their manipulation and dynamics under electric field.

"We have known about the phenomenon of ferroelectricity for a good hundred years. But it is only in recent years that exotic polar textures have been unveiled. This opens up exciting possibilities for revolutionary new materials and devices. This is definitely the best time to be at the forefront of this field of research," says Dubourdieu.

    Superconducting TES array X-ray spectrometer goes into operation at BESSY II
    The 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.

    Magnon momentum microscopy: A new window into nanoscale spin-waves
    An 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.

    X-ray analysis reveals overpainted fascist symbols
    Erich 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.
