Selection of research fields
Selection of research fields: Artificial granular lattices combining ferromagnetic and superconducting grains. Super-para to super-ferromagnetic transition. Granular superconductors. Homogeneous solid state materials close to a metal/superconductor-insulator transition.

Our group is concerned with the consequences of electronic correlation effects and disorder on the properties of thin films and nanostructures. In particular, we are interested in cooperative ground states, such as magnetism and superconductivtiy in the proximity to a metal-insulator transition.

The main focus of our scientific work is on granular electronic systems, such as nano-granular metals, ordered and disordered arrays of magnetic nano-elements, superconducting nanostructures, and artificially granulated meta-materials, such as ferroelectric organic charge transfer systems combined with nano-granular metals.

For sample preparation we use mainly the direct-writing method of focused electron beam induced deposition (FEBID) and different thin film growth techniques, such as molecular beam epitaxy and sputtering.

In an application-oriented facet of our research we also evaluate concepts for the use of correlation effects in sensor development (strain, magnetic stray field, and dielectric sensing).
