Molecular Materials: Electronic Properties
Einzelmolekülkontakt
Molecular materials are exciting for physics because they combine the almost infinite design space of chemistry with the complexity of materials. Questions in our group include:
- How does current flow through a single molecule?- How can we measure and understand the thermoelectricity of single molecules?- How can we understand the interaction of the two-dimensional, atomically thin carbon material graphene with molecules?
At FAU, we work on molecular materials in a joint research approach of physics, chemistry and materials science. For this purpose, we are organized, among others, in the Interdisciplinary Institute for Molecular Materials (ICMM) and in the collaborative research center "Synthetic Carbon allotropes" (CRC 953).
Projects
SFB 953: Graphene and Organic Molecules: Transport Experiments (B08)
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…
