Molecular Clusters of Transition Metal Chalcogenides

(A. Eichhöfer, O. Fuhr, D. Fenske)

Molecular Transition Metal Clusters of Sulfides, Selenides or Tellurides are synthesized and structurally characterized in order to investigate how size, composition and structure influence the electronic properties of these nanoobjects. Important tools are inert gas atmosphere techniques, single crystal XRD, optical spectroscopy and magnetic measurements.
In addition we study the fabrication of metastable nanoscopic binary and ternary solids from cluster molecules through low temperature thermolysis.
