Jan Lüning heads HZB Institute for Electronic Structure Dynamics

© HG Medien

The HZB Institute for Electronic Structure Dynamics, newly founded on 1 May, develops experimental techniques and infrastructures to investigate the dynamics of elementary microscopic processes in novel material systems. This will help to optimise functional materials for sustainable technologies.

Prof. Dr. Jan Lüning is an internationally recognised expert in research with synchrotron radiation. Before joining HZB in 2018, he was a professor at Sorbonne University in Paris and worked at the French synchrotron SOLEIL.

Three groups belong to the institute: Dr Ulrich Schade's group operates the IRIS infrared beamline at the BESSY II synchrotron radiation source. He examines molecular processes in novel functional materials that enable, for example, energy conversion or catalytic water splitting.

The group "Ultra-Short-Time Laser Spectroscopy" led by Dr. Iain Wilkinson works in the laser laboratories ULLAS and LIDUX and investigates the dynamics of reactions in aqueous solutions and at aqueous interfaces on ultra-short time scales.

The third group, led by Dr. Christian Schüssler-Langeheine and Dr. Niko Pontius, operates the Femtoslicing Facility at BESSY II and conducts research on materials with complex phase transitions that have the potential to make electronic and magnetic devices smaller, faster and more energy efficient.

The institute's research activities are part of the Helmholtz Association's Programme-Oriented Funding (POF IV) in the Research Field Matter.

    Unconventional piezoelectricity in ferroelectric hafnia
    Hafnium oxide thin films are a fascinating class of materials with robust ferroelectric properties in the nanometre range. While their ferroelectric behaviour is extensively studied, results on piezoelectric effects have so far remained mysterious. A new study now shows that the piezoelectricity in ferroelectric Hf0.5Zr0.5O2 thin films can be dynamically changed by electric field cycling. Another ground-breaking result is a possible occurrence of an intrinsic non-piezoelectric ferroelectric compound. These unconventional features in hafnia offer new options for use in microelectronics and information technology.

    14 parameters in one go: New instrument for optoelectronics
    An HZB physicist has developed a new method for the comprehensive characterisation of semiconductors in a single measurement. The "Constant Light-Induced Magneto-Transport (CLIMAT)" is based on the Hall effect and allows to record 14 different parameters of transport properties of negative and positive charge carriers. The method was tested now on twelve different semiconductor materials and will save valuable time in assessing new materials for optoelectronic applications such as solar cells.

    Sodium-ion batteries: How doping works
    Sodium-ion batteries still have a number of weaknesses that could be remedied by optimising the battery materials. One possibility is to dope the cathode material with foreign elements. A team from HZB and Humboldt-Universität zu Berlin has now investigated the effects of doping with Scandium and Magnesium. The scientists collected data at the X-ray sources BESSY II, PETRA III, and SOLARIS to get a complete picture and uncovered two competing mechanisms that determine the stability of the cathodes.
