The module provides insights into the synthesis and the surface nanophysics of functional, electrically responsive polyoxometalate-based materials. These molecular metal-oxide clusters can be widely chemically modified, e.g. for specific surface adsorption properties or biocompatibility via DNA-functionalization. Both classical solution-based deposition methods and highly advanced techniques such as ion-beam based ion soft-landing, 3D bio-printing, and photon-based UV-light curing for the controlled deposition and structuring of polyoxometalate compounds on different surface-types will be introduced, as well as important analytical surface methods such as scanning tunneling microscopy and spectroscopy. Besides the pure surface characterization, the latter technique also allows the electron-induced redox switching and the surface modification of the deposited components on the nanoscale. Further, the actual and potential application of these molecular materials in the fields of computing, sensor technology, and medicine will be discussed.
