Electronic correlations, disorder and cooperative phenomena in thin films and nanostructures
Our group is concerned with the consequences of electronic correlation effects and disorder on the properties of thin film systems and nanostructures which show cooperative ground states, such as superconductivity and magnetism, or exhibit a correlation-driven metal-insulator transition. Our research focuses on three material classes. These material classes are the heavy fermion superconductors, organic charge transfer salts and granular electronic systems. Aspects of applied research, such as sensor functionality, are covered in our work on ferromagnetism and charge transport in (granular) nanostructures.
