The research of Prof. Dr. Elke Scheer is mainly focused in the field of mesoscopic physics with strong emphasis on nanoelectronics where novel electronic transport phenomena in reduced dimensions are explored. Her research interests include the study of mesoscopic superconductivity in hybrid systems consisting of superconductors and non superconducting materials. In collaboration with Dr. Torsten Pietsch a variety of spin transport phenomena and nanomagnetism are studied in nanostructures down to the atomic scale.
Another important research activity is given by the field of molecular electronics devoted to the study of electric and thermoelectric properties of single-molecule junctions with the aim to unravel their transport mechanisms.
Jointly with Prof. Dr. Johannes Boneberg, Elke Scheer follows her research interests in nanooptoelectronics, in which optical fields and nanoplasmonic elements are used to control the transport through atomic size conductors.
Finally the vibrations of nanomembranes are explored as alternative control knob of the electronic transport behavior of atomic and molecular size circuits.
The research of Dr. Torsten Pietsch is dedicated to the development and physics of hybrid nanodevices. He is particularly interested in interface-controlled nanostructures of correlated electronic systems, such as mesoscopic superconductivity and magnetic nanostructures, as well as self-assembled functional nanomaterials, where the coupling of spin and charge with other degrees of freedom manifests itself in novel (collective) properties. The group explores spin- and charge transport phenomena in these systems with a special emphasis on static electronic properties, non-linear dynamics and light-matter interaction in the GHz and THz regime.
In the group of Prof. Dr. Johannes Boneberg the interaction of light with nanostructures as well as the application of light for the formation of nanostructures is studied in the following project areas:
- pulsed laser interference lithography
- optical nearfields
- dewetting of metals
- control of magnetic domains and domain walls by thermal gradients
The research of PD Dr. Regina Hoffmann-Vogel focuses on high-resolution low temperature scanning force microscopy. For the purpose of understanding electrostatic and covalent tip-surface interaction and contrast formation we study insulators such as ionic crystalline surfaces (KBr, NaCl, CaF2) experimentally as well as by simulations and semiconductors, mainly Si(111). We also investigate molecules on metallic or ionic crystalline surfaces as thin molecular layers or islands. The properties we are interested in are the structure, the local work function and charge, and all surface forces in general. We combine scanning force microscopy in vacuum with electronic transport at the nanoscale and electromigration studies.
