NFDI Consortium FAIRmat recommended for funding

A team led by Claudia Draxl, who is a member of IRIS Adlershof, has reached a key milestone: The FAIRmat consortium, which Draxl constituted, was recommended for funding by the NFDI expert panel of the German Research Foundation (DFG) on May 10. This is an important success in the three-stage application process to establish the National Research Data Infrastructure (NFDI). FAIRmat applied together with 16 other consortia in October 2020 and already received positive feedback at the beginning of the year on the virtual review that took place in December 2020. The final funding decision will be made by the Joint Science Conference (GWK) in early July. The aim of the national research data infrastructure (NFDI) is to systematically manage scientific and research data, provide long-term data storage, backup and accessibility, and network the data both nationally and internationally. FAIRmat represents the interests of experimental, theoretical and computational condensed matter physics and materials science.

IRIS Adlershofcongratulates and keeps its fingers crossed!

Launch of the first Einstein Research Unit of the Berlin University Alliance on the topic of quantum computing

Quantum computers are seen as one of the key technologies of the 21st century. Can they revolutionize the computational capacity of computers? Which new insights do they offer for high energy physics or quantum chemistry? These are the questions on which the first Einstein Research Unit (ERU) of the Berlin University Alliance (BUA) will be focusing. The interdisciplinary research team of the partners Free University of Berlin, Humboldt-Universität zu Berlin, Technical University of Berlin and Charité - Universitätsmedizin, which includes IRIS Adlershof members Prof. Dr. Oliver Benson and Dr. Tim Schröder, has made it its task to explore the potential of the quantum digital transformation. They will combine expertise in theoretical and experimental physics, applied mathematics, computer science and machine learning in a unique way. The Einstein Research Unit „Perspectives of a quantum digital transformation: Near-term quantum computational devices and quantum processors“ will initially receive two million Euros in funding over the next three years.

Successful collaboration with industry in joint paper on inkjet-printed electrodes in OLEDs

Researchers in the HySPRINT joint lab Generative Manufacturing Processes for Hybrid Components (GenFab) of Humboldt-Universität zu Berlin (HU) and Helmholtz-Zentrum Berlin (HZB) have successfully implemented an ink produced by the Berlin-based company OrelTech in solution-processed organic light emitting diodes.

After inkjet printing the particle-free silver ink, an argon plasma is used to reduce the silver ions in the ink to metallic silver. “Because this process takes place at a low temperature, it is suitable for use with temperature-sensitive substrates, such as flexible plastic foils,” explains Dr. Konstantin Livanov, co-founder and CTO of OrelTech. The researchers fabricated organic light-emitting diodes employing the silver ink as a transparent conductive electrode on the flexible substrate PET. The resulting devices show comparable light output characteristics to those based on the otherwise widely used indium tin oxide (ITO). Crucially, however, the silver electrodes showed superior stability to ITO upon mechanical bending. Dr. Felix Hermerschmidt, senior researcher in the joint lab of HU and HZB, confirms, "The OLEDs based on the OrelTech ink remain intact at a bending radius at which the OLEDs based on ITO show breakage and fail.” This opens up several application opportunities of the printed devices. The work has been published in the journal Flexible and Printed Electronics and is available Open Access. GenFab, led by Prof. List-Kratochvil, who is a member of IRIS Adlershof, is moving into laboratories and offices in the new IRIS research building for further research and development work.
