Molecular Materials: Light/Matter Interface
Light-matter coupling of a point-like light source
Molecular materials are exciting for physics because they combine the almost unlimited design space of chemistry with the complexity of materials. Among others, questions in this area are: Why does light emerge when electrons tunnel? How can I excite and understand electronic processes in perowskites with light? How can I influence excitons in molecular solids?
In these fields we collborate intensively with our colleagues from material science and chemistry.

Wir werden Experimente durchführen, in denen wir das Zusammenspiel von Graphen und organischen Molekülen mit elektrischen Methoden messen können. Wir beabsichtigen Einzelmolekülkontakte und flächige Graphen-Molekül-Graphen-Kontakte herzustellen, deren elektrische Transporteigenschaften wir detailliert untersuchen. Als Moleküle werden Polyyn-Drähte und andere molekulare Drähte verwendet. Weiterhin sind Moleküle mit Fulleren-Endgruppen von besonderem…

RTG2861-PCL is a collaboration between Technische Universität Dresden (TUD) and Friedrich-Alexander Universität Erlangen-Nürnberg (FAU), and is funded by Deutsche Forschungsgemeinschaft. Our goal is to achieve atomic-precision synthesis and exploration of new planar carbon lattices (PCLs) for next-generation quantum materials, functional precision membranes, optoelectronic and electrochemical devices, by employing advanced experimental and theoretical methods in an interdisciplinary approach bridging synthetic chemistry, condensed-matter physics, and materials science. Our dual-site TUD & FAU collaboration will establish the standard in research-based education in the field of PCL by combining our expertise in synthesis, function exploration, and theoretical description, and by exploiting the complementarity in laboratory equipment available at our institutions.
