New BMBF junior research group “Diamond Nanophotonics for On-Chip Quantum Technology” as part of the BMBF Quantum Future funding

Since October Dr. Tim Schröder has been forming a junior research group on “Spin-defect centers in nanophotonic circuits for quantum information processing” at the Physics Department of the Humboldt-Universität zu Berlin. His group will be funded by a five-year BMBF project “Diamond nanophotonics for on-chip quantum technology” within the framework of the program Quantum Futur. Before his return, Dr. Schröder who finished his doctoral studies at the Humboldt-Universität zu Berlin in 2012 spent the last four years as a researcher at the Massachusetts Institute of Technology (MIT, USA) and two years as an assistant professor at the Niels Bohr Institute (NBI, Denmark) where he worked on hybrid integrated photonic systems to control individual spin-based quantum memories in diamonds and gallium arsenide. His research was awarded the Carl Ramsauer Prize and has been funded by a Feodor Lynen scholarship from the Alexander von Humboldt Foundation and a Marie Sklodowska Curie fellowship from the European Union. At Humboldt-Universität zu Berlin, Dr. Schröder will continue to work on these topics while taking advantage of the resources that  IRIS Adlershof has to offer. For example, he will collaborate closely with the nano optics research group of Prof. Oliver Benson who is also an IRIS member.

The overall scientific goal of the project “Diamond Nanophotonics for On-Chip Quantum Technology” is to combine defect centers in diamonds and nanophotonic structures into compact, hybrid on-chip modules and then to demonstrate their operational interconnections, which will be a crucial step towards quantum information processes based on optically active solid state materials. Defect centers that interconnect with high rates form the basis for quantum networks, which can be used for remote quantum communication or complex quantum computing. IRIS Adlershof wishes Dr. Schröder much success in obtaining these goals and is looking forward to a fruitful collaboration.



The President of Universidade de São Paulo visits Adlershof

The president of the Universidade de São Paulo (USP), Professor Vahan Agopyan, as well as USP’s vice-president for International Relationships, Professor Raul Machado Neto, visited within the framework of a several day Berlin stay to inform themselves as well about the current study conditions and opportunities to do research at the natural science campus of Humboldt-University zu Berlin (HU).

Prof. Jan Plefka, the vice dean for research at the HU’s mathematics and natural science department and a member of IRIS Adlershof, and Dr. Nikolai Puhlmann, IRIS’s managing director, gave an overview of the HU’s natural science campus and IRIS Adlershof’s concept and development. They also gave details on the IRIS research building still under construction. Prof. Ulf Leser and Prof. Henning Meyerhenke from the Department of Computer Science informed the guests about their department’s current research plans and projects.

The HU and USP’s jointly run international research training group IGRT 1740 „Dynamical Phenomena in Complex Networks: Fundamentals and Applications“ was introduced to the guests in detail by the research training group’s speaker, Prof. Jürgen Kurths (Potsdam Institute for Climate Impact Research and HU Berlin). At the end of their visit, the guests saw the prototype of a Cherenkov telescope that is being erected in Adlershof within the framework of the international major project
Cherenkov Telescope Array (CTA) in which the HU and USP are both participating. Prof. Thomas Lohse from the Department of Physics at the HU described how the telescope functioned and the scientific focus of the CTA project.

The São Paulo guests were very interested in and impressed by the progress made in the HU’s research results and praised the diverse opportunities that Adlershof science site has to offer for top-ranking natural science research and the education of international young scientists.

The Universidade de São Paulo (USP) is one of three strategic profile partners of the Humboldt University and consistently ranks one of the top universities in the South American subcontinent.

We congratulate the participating researchers and look forward to a good cooperation!


Printing solar cells and organic LEDs - HZB & HU cooperate

Humboldt-Universität zu Berlin and Helmholtz-Zentrum Berlin form a joint lab and research group “Generative production processes for hybrid components”.
Solar cells, LEDs and detectors made of organic and hybrid semiconductors can nowadays be simply printed out, even together with teensy nanostructures that make them function better. The development of low-cost printing methods for electronic and optoelectronic components is at the centre of things for the new joint research group and the joint laboratory of the Helmholtz-Zentrum Berlin (HZB) and Humboldt-Universität zu Berlin (HU).

Cooperating together in the new research group are the HU workgroup “Hybrid Devices” led by Prof. Dr. Emil List-Kratochvil, the HZB young investigator group of Dr. Eva Unger, the Helmholtz Innovation Lab HySPRINT, and the Competence Centre Photovoltaics Berlin (PVcomB) directed by Prof. Dr. Rutger Schlatmann. The partners are building up a joint lab at Humboldt-Universität zu Berlin that will allow the researchers to acquire and use complementary laboratory infrastructures for various coating methods.
Prof. Emil List-Kratochvil is the head of the HU workgroup “Hybrid Devices” at IRIS Adlershof, and has been working for 15 years on developing electronic and optoelectronic hybrid components, resource-efficient deposition techniques (inkjet printing) and in-situ nanostructuring and synthetic methods. This expertise complements the aims of the HZB young investigator group led by Dr. Eva Unger. She will be developing solution-based manufacturing methods for depositing perovskite semiconductor layers onto larger surface areas for solar cells. “The new research group with List-Kratochvil is a real win for us. With his experience in printed electronic components, he is an ideal cooperation partner for us,” Unger says.
In recent months, the researcher and her team have already come much closer to her goal of developing hybrid tandem solar cells with large-surface-areas in the scope of the Helmholtz Innovation Lab HySPRINT. Now, the next step is to upscale the process in order to drive the novel solar cells towards market maturity. The Competence Centre Thin-Film- and Nanotechnology for Photovoltaics Berlin (PVcomB) is the ideal partner for the development of industrially relevant manufacturing processes. The joint research group is now striving towards building a pilot line on which to develop prototypes of hybrid components.
