What is already established for inorganic semiconductors stays a challenge for their organic counterparts: Tuning the energy gap by blending different semiconducting molecules to optimize device performance. Now, scientists from TU Dresden, in cooperation with researchers at TU Munich, as well as University of Würzburg, HU Berlin, and Ulm University demonstrated how to reach this goal.

Einmal scannen und sofort die wichtigsten Informationen im Überblick… was Lesesensoren im Smartphone bei QR-Codes heute schon selbstverständlich leisten, sollen neuartige Sensoren künftig auch in vielen anderen Bereichen möglich machen.
Am landesgeförderten Kurt-Schwabe-Institut in Waldheim (Meinsberg) im Landkreis Mittelsachsen wird an diesen Technologien geforscht. Wissenschaftsminister Sebastian Gemkow und Regionalentwicklungsminister Thomas Schmidt haben das KSI gemeinsam besucht und sich einen aktuellen Eindruck von der Forschungsleistung verschafft.
In a joint experimental and theoretical effort between Lund University (Sweden), the Russian Academy of Sciences (Russia), and the Center for Advancing Electronics Dresden at Technische Universität Dresden (Germany), researchers developed a novel spectroscopic technique for the study of charge carrier dynamics in lead halide perovskites - publication in the renowned journal Nature Communications.
Scientists at the Institute of Science and Technology Austria (IST Austria) and at the Center for Advancing Electronics Dresden (cfaed / Technische Universität Dresden) show that little differences in behavior decide between success and complete failure of epidemic control. In their study, the scientists were able to show that limits in testing and contact tracing are responsible for this sudden change in the epidemic outcome. Testing followed up by contact tracing is extremely efficient in slowing down epidemics, however once their limit is exceeded the epidemic accelerates resulting in a faster than exponential spread. The study was published in the journal Nature Communications.
An interdisciplinary research team from TU Dresden at the Chair of Network Dynamics headed by Prof. Marc Timme (Center for Advancing Electronics Dresden – cfaed & Institute of Theoretical Physics) has studied people's motivation to use "shared mobility" offers. In ride-sharing, trips of two or more customers with similar origins and destinations are combined into a single cab ride. The concept can make a significant contribution to sustainable urban mobility. However, its acceptance depends on human needs and behavior. For example, while shared rides typically offer a financial advantage, passengers might suffer drawbacks in terms of comfort and trip duration. These factors give rise to different adoption behaviors that explain usage patterns observed in 360 million real-world ride requests from New York City and Chicago in 2019. The study has now been published in the journal Nature Communications.
