Interfaces between transition metal dichalcogenides and weakly interacting molecules
Electronic properties of layered transition metal dichalcogenide (TMDC) surfaces might be tuned by the adsorption of molecules. While this was shown for strong electron acceptors, interfaces between weaker interacting, physiosorbed carbon molecules and TMDCs were studied only in exceptional cases. On the other hand, the influence of the adsorption of such molecules on optoelectronic properties of TMDCs was clearly demonstrated.

Most topics are related to interfaces and growth of organic materials
Electronic properties of interfaces of organic materials are one focus of current research. Models that have been established for inorganic semiconductor interfaces, cannot be directly adapted to organic systems. Charge transfer processes and polarization phenomena decisively determine the interfacial properties. The work will be mainly carried out with photoemission and scanning tunneling microscopy in our home lab and at synchrotron radiation sources. Please ask for further information.
