CRC 951 researchers Max Heyl and Emil List-Kratochvil report on novel TMDC exfoliation technique at Advanced Science News

Pressing a layered crystal onto a gold surface is all it takes to pull off a 2D atomic layer, a method that outperforms scotch tape on industrially relevant scales. Read the article at Advanced Science News to learn more about this new technique.

CRC 951 “Hybrid Inorganic/Organic Systems for Opto-Electronics (HIOS)” successful to launch third funding period

The Collaborative Research Centre 951 "HIOS - Hybrid Inorganic / Organic Systems for Opto-Electronics" (HIOS) will receive funding for another four years. This was decided by the German Research Foundation (DFG) at this years’ spring meeting in Bonn.

Since its establishment in 2011, the development and investigation of innovative hybrid systems has been the scientific focus of the CRC 951. These hybrid systems combine inorganic semiconductors, conjugated organic materials, and metal nanostructures with long-term goal to realize novel and superior opto-electronic functions in the meso- or nanoscopic range not achievable with any of the individual material classes alone. These functions could be used, for example, in high-frequency and multi-colored light sources and sensors, as well as electronic and optical multifunctional devices of future generations of information technology.

In the past years, the CRC elucidated the fundamental chemical, electronic, photonic, and plasmonic interactions arising from the different nature of the components combined in HIOS. As one of many results, novel hybridized quantum states and coupled excitations at the inorganic/organic interfaces were uncovered. These impressive results laid the foundation for the next four years of exciting HIOS-research.

The German Research Foundation (DFG) has now acknowledged the achievements of the CRC 951 by granting a third funding period for 2019 – 2023. The CRC's spokesperson and deputy spokesperson, Norbert Koch and Oliver Benson look forward to the joint work with 21 principal investigators from physics and chemistry of Humboldt-Universität zu Berlin (coordinating university), Technische Universität Berlin, Freie Universität Berlin, Universität Potsdam, Helmholtz-Zentrum Berlin für Materialien und Energie, and Fritz-Haber-Institut der Max-Planck-Gesellschaft.

Dr. Raphael Schlesinger’s dissertation released by Springer Theses ▼

The dissertation of Dr. Raphael Schlesinger was selected to be published in Springer Theses, a dedicated book series to recognize outstanding doctoral research. His work, conceived and performed within the SFB951 at the Institut für Physik of Humboldt-Universität zu Berlin, was supervised by Prof. Norbert Koch, also member of IRIS Adlershof.

The thesis unravels fundamental mechanisms governing hybrid inorganic organic energy-level alignment and its purposeful manipulation.These insights pave the way towards new technological control and enable usage of hybrid materials and interfaces in future devices and applications.

CRC 951 "Hybrid Inorganic/Organic Systems for Opto-Electronics (HIOS)" successful to launch second funding period (2015-2019) ▼

May, 2015


CRC 951 scientists perform cutting-edge research on hybrid systems that unite inorganic semiconductors, metal nanostructures, and conjugated organic materials, with the aim to realize and tailor novel opto-electronic functions. The achievements made during the first funding period (2011-2015) laid the foundations for the next four years of exciting HIOS-research. In the long term, the CRC aims for solid-state opto-electronic devices that exhibit superior performance compared to those based on any of the individual material classes alone.

The CRC's coordinator and vice-coordinator, Norbert Koch and Oliver Benson, are delighted with the success in obtaining continued funding from the Deutsche Forschungsgemeinschaft (DFG), and they look forward to the joint work of 25 principal investigators from physics and chemistry of Humboldt-Universität zu Berlin (coordinating university), Technische Universität Berlin, Universität Potsdam, Helmholtz-Zentrum Berlin für Materialien und Energie, and Fritz-Haber-Institut der Max-Planck-Gesellschaft.

Humboldt-Spektrum, Jan, 2012


Im kürzlich etablierten Sonderforschungsbereich 951 >>Hybrid Inorganic/Organic Systems for Opto-Electronics<< (HIOS), werden neuartige Hybridmaterialien entwickelt, die aus anorganischen Halbleitern, konjugierten organischen Molekülen und Metall-Nanostrukturen zusammengesetzt sind. Ziel ist es, die Vorteile der Einzelmaterialien zu kombinieren, Nachteile zu kompensieren und damit bessere und neuartige Funktionseigenschaften zu erhalten, die mit keinem der individuellen Konstituenten allein erreichbar wären.
