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.

SFB 953: Graphene and Organic Molecules: Transport Experiments (B08)

Term: since January 1, 2012
Funding source: DFG / Sonderforschungsbereich (SFB)
Project leader: Heiko B. Weber

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…
