In future, electronics will be controlled via light waves instead of voltage signals: This is the goal of physicists worldwide. The advantage: Electromagnetic waves of light oscillate at the petahertz frequency. This means that future computers could be a million times faster than the current generation. FAU scientists have now come one step closer to this goal: They have succeeded in precisely controlling electrons in graphene with ultra-short laser pulses.

If you look up at the sky on a clear night you can see stars, lots of stars. Astronomical recordings from observatories let you see them in much greater detail. The Dr. Remeis Observatory in Bamberg, which belongs to Friedrich-Alexander-Universität Erlangen-Nürnberg, owns approximately 40,000 historical photographic plates, a genuine treasure trove for anyone interested in stargazing. Together with Leibniz-Institut für Astrophysik Potsdam and the Universities of Hamburg and Tartu (Estonia), astronomers at FAU have now digitalised roughly 70,000 such glass plates and published them online at www.plate-archive.org.

Physicists at FAU have proven that incoming light causes the electrons in warm perovskites to rotate thus influencing the direction of the flow of electrical current. They have thus found the key to an important characteristic of these crystals, which could play an important role in the development of new solar cells. The results have now been published in the renowned journal ‘Proceedings of the National Academy of Sciences’.

Physicists at the Friedrich Alexander University Erlangen-Nürnberg (FAU), the University of Hamburg and the research facility DESY have succeeded for the first time in revealing tiny structures using an imaging method that relies on the usual diffraction of light, but which does not require the scattered light to be coherent. With conventional imaging methods using the diffraction of coherent light, scientists have to go to considerable lengths to ensure the coherence of the radiation, i.e. the electromagnetic waves must remain in phase during the scattering process. The new method uses incoherent light instead.

Assembling electronic building blocks from single molecules is a main objective in nanotechnology. An interdisciplinary research group at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) has made a major step towards this goal. The groups of Prof. Dr. Sabine Maier, Prof. Dr. Milan Kivala und Prof. Dr. Andreas Görling have suceeded in assembling and investigating wires and networks from newly developed single molecules as building blocks. These could form the basis for future opto-electronic devices like flexible screens or sensors. Their work has been published in „Nature Communications“.
