Research Interests

  • Synthesis and structural characterization of binary and ternary semiconductor cluster molecules composed of transition metals in combination with chalcogen elements.   
  • Single crystal and powder X-ray analysis.   
  • Investigation of size dependent properties (Quantum size effect) of the as synthesized nanoclusters including optical, electronic and magnetic properties.
  • Thermal decomposition (TGA, DSC) of the cluster molecules in order to fabricate new nanostructured and / or metastable binary and ternary phases for e. g. use as battery materials.
