Research groups at the institute

Department: Atomic and Molecular Structures

Group Ding

We conduct research where semiconductor physics and quantum optics meet. The development of novel nanomaterials is thereby the foundation for building up a solid state quantum photonic network for applications in quantum communication and metrology.

light & matter group

The central goal of our research is to experimentally research on the ultimate limits of single emitter and single photon spectroscopy. This includes their detection, their microscopic localization, and the sensing of single emitters and their environment.

In some experiments we couple single molecules to other quantum objects, such as silver nanowires, atomic vapors, etc.. The combination of single solid-state emitters and the narrow-band features of an atomic system opens up a novel field of quantum-hybrid systems. Our research on single molecules has been very influential to other areas, such as the research on quantum dots and single atoms.

For quantum sensing and quantum optics we utilize hot atomic vapors, which represent a very robust line of quantum technologies.

Quantum hacking is the vital combination of quantum information, information theory and the daily quest to extend our view on information security. We perform real-word quantum cryptography, which is more than simply sending single photons from A to B.

Group Pfnür

We study the physical and chemical properties of ultra-small nano-objects that become more important with the advancing minituarization. These properties are strongly determined by their boundary surfaces, which we wan to modify and control in a deterministic fashion. We therefore connect solid state physics in low dimensions with the studies of quantum objects and chemistry.

Our group focuses on the development and implementation of new optical components and setups, as well as the metrological characterization of single photon emitters and detectors, for their application in quantum technologies.

Department: Nanostructures

Group Haug

Quantum effects in low-dimensional electron systems are fundamental for the quantum computer realization. Benefitting from our long-standing experience in the field of nanostructured semiconductors we examine the electronic properties of several quantum systems.

Group Oestreich

Our research group has long-standing experience in the fields of spin and charge carrier dynamics in complex semiconductor nanostructures as well as concerning the methods of spin noise spectroscopy, ultrafast spectroscopy and Magneto-Optics.
The diverse spectrum of investigated semiconductor nanosystems ranges from bulk GaAs and ultra pure Silicon to two-dimensional transition metal dichalcogenides and up to single holes localized in InGaAs quantum dots.

Department: Solar Energy

Group Brendel

Together with the ISFH we are working on the continuous development and improvement of solar cells. In this regard, we are working on simulations and calculations of phenomena that are important for the analysis, characterization and optimization of solar cells and modules

Group Schmidt

The group Schmidt works on various aspects of photovoltaic materials research, with the experimental work being carried out mainly at ISFH. Main topics include research on defects and defect reactions in semiconductors for photovoltaics as well as charge carrier selective coatings for next generation solar cells.
