Experimentelle Physik VI




    University of Würzburg newspaper einBLICK interviewed Dr. Hannes Kraus about his recent Nano Letter paper, the  Takasaki-Würzburg project on 3D-writing of spin defects in silicon carbide as well as on his future plans. More.


    Congratulation to Dr. Georgy Astakhov, who was awarded with the Habilitation degree in Experimental Physics for his work “Intrinsic Defects in Silicon Carbide for Quantum Application” after giving the public lecture entitled „Perowskite: eine Struktur mit drei einzigartigen Eigenschaften“. Habilitation is the highest post-doctoral qualification level issued by German universities and is the key for access to a professorship.


    Congratulation to our Silicon Carbide group! Two manuscripts were accepted for publication in high impact journals nearly at the same time, the one on „3D Proton Beam Writing of Optically Active Coherent Vacancy Spins in Silicon Carbide" by Hannes Kraus et al. in Nano Letters and the other one on „Locking of Electron Spin Coherence Above 20 ms in Natural Silicon Carbide“ by Dimitri Simin et al. in Phys. Rev. B. The latter paper has been selected by the editors of PRB to be an Editors’ Suggestion. Have a look at our list of publications.



    Congratulations to Hannes Kraus, who has been awarded a NASA Postdoctoral Program Fellowship at the NASA Jet Propulsion Laboratory. The NASA Postdoctoral Program is extremely selective, and this Fellowship is a recognition of his highly ranked academic and scientific achievement.


    Germany’s international broadcaster Deutsche Welle posted a video on Organic Solar Cells taken in our EP6 labs. Watch the video.


    Congratulations to our perovskite group, who published its recent findings related to various recombination mechanisms in the ACS and NPG journals. In particular, in the ACS Energy Letters they demonstrated how to reduce the shunt and surface recombination by employing polyarylamine as electron transport layer. This work was done in collaboration with our partners from the University of Valencia, Spain. In Scientific Reports they demonstrated how to improve charge carrier lifetime in planar perovskite solar cells by bromine doping. Have a look at our list of publications.




    DFG and the Austrian FWF approved the bilateral proposal "Quantum Control of Spin Centers in Silicon Carbide with Microcavities" under D-A-CH Lead-Agency. The purpose of this project is to realize light matter interfaces based on optically active defects in SiC. Project partners are Dr. Georgy Astakhov, EPVI, Uni Würzburg and Dr. Michael Trupke from Vienna Center for Quantum Science and Technology, TU Vienna.


    DFG and the Russian Science Foundation (RSF) approved the bilateral proposal "Polytype and isotope engineering of silicon carbide for quantum microwave amplifiers". The purpose of this project is to demonstrate quantum microwave amplification in SiC. Project partners are University of Würzburg and Ioffe Institute, Saint Petersburg, Russia. 14 Russian-German research proposals (of more than 120) will be funded under the framework of this first joint call.


    Good news from Brussels! Horizon 2020 Project SEPOMO - Spins for Efficient Photovoltaic Devices based on Organic Molecules was selected for funding. The project objective is to clarify the role of electron spins of photo-generated species in the efficiency of organic solar cells. The EU Commission has granted ca. 4 Mio. Euro to pursue this research and training network in 6 European countries in the coming 4 years.



    Congratulations! The proposal DIABASE “Highly sensitive diamond and carborundum nano-sensors and bio-markers with NIR optical addressability”, submitted under the ERA.Net RUS Plus initiative has been selected for funding. Project partners are: Würzburg / Germany (as Coordinator), Ulm and Stuttgart / Germany, Moscow and St. Petersburg / Russia, Vienna / Austria, Krakow / Poland, Tallin / Estonia,
    Turku / Finland.


    Congratulations to Katrin Anneser, ZAE Bayern and EP6. Her project "Development of an energy efficient solar energy storage system based on a printed solar cell and supercapacitor" will be funded by Deutsche Bundesumweltstiftung (DBU).

    "Engineering near infrared single photon emitters with optically active spins in ultrapure silicon carbide"

    Our new publication on room-temperature single-emitters based on spin centers in SiC: The work entitled "Engineering near infrared single photon emitters with optically active spins in ultrapure silicon carbide" has been accepted for publication in Nature Communications. Have a look at the preprint at arXiv:1407.7065.


    The German Research Council (DFG) established a new Research Training Group (GRK2112) Molecular Biradicals: Structure, Properties and Reactivity, in which EP6 is participating. See also the press release of the University of Würzburg (in German).
