New method finds defects in power transistors more accurately, quickly and simply Transistors are needed wherever current flows, and they are an indispensable component of virtually all electronic switches. In the field of power electronics, transistors are used to switch large currents. However, o...

Being able to control electronic systems using light waves instead of voltage signals is the dream of physicists all over the world. The advantage is that electromagnetic light waves oscillate at petaherz frequency. This means that computers in the future could operate at speeds a million times faster than those of today. Scientists at FAU have now come one step closer to achieving this goal as they have succeeded in using ultra-short laser impulses to precisely control electrons in graphene.

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

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’.

From July 23 - 26, 2018 the Max Planck Institute for the Science of Light is celebrating three important anniversaries in Erlangen optics: 150 years of optics research in Erlangen, the 15th anniversary of the establishment of the Max Planck Research Group for Optics, Information and Photonics (the precursor of the Max Planck Institute for the Science of Light, MPL), and 1.5 years of the inauguration of the new MPL building.
