Research Topics
We are an inorganic chemistry group at the Institute of Nanotechnology Forschungszentrum Karlsruhe. We aim to produce molecular building blocks which can be processed into nanoscale devices or else already show useful properties at the nanoscale level. In order to characterise these building blocks we gain precise structural information at atomic resolution using X-ray diffraction as well as measuring a range of physical properties such as magnetism and electron transport. The systems under study include ligand-stabilised metal cluster compounds; metal-organic frameworks (MOFs); the use of crystal engineering to tailor properties and build multifunctional materials.
Outlook
The compounds we synthesise will be further processed to build into devices. Thermal processing allows access to materials with a range of possible applications, such as anode materials for batteries or else stoichiometrically precise oxide nanoparticles. The deposition of nanoclusters as films or ordered arrays allows for the addressing of systems.
Current Projects

The research target is the synthesis of metal chalcogenide cluster molecules. Main issues are the investigation of the quantum size effect, the functionalisation of the ligand shell and the fabrication of metastable nanoscopic binary and ternary solids from cluster molecules through low temperature thermolysis.
