Research groups

Research at PGI-9 can currently be broken down into seven sub-areas:

Quantum transport in nanostructures

In Thomas Schäpers 's research group, the transport properties of nanostructures based on semiconductor nanowires, topological structures and high temperature superconductors are investigated.

Silicon-based epitaxy and photonics

Dan Buca 's group is working on the development of materials from the 4th main group of the periodic table that can be monolithically integrated into current silicon technology. We are working on Si-Ge-Sn heterostructures for high-performance photonic and electrical devices such as room temperature lasers and infrared detectors. Recently we investigate the thermoelectric and magnetic properties of these materials.

Topological and superconducting quantum devices

In Peter Schüffelgen 's group, we are working on the construction and characterization of novel topological and superconducting devices for topological and superconducting quantum computing.

Quantum photonics

In Beata Kardynal 's group, we explore the interactions of light with semiconductor nanostructures and defects in solids. We also explore exotic states in two-dimensional materials (e.g. hBN and transition metal dichalcogenides, TMDCs).

Epitaxy of topological insulators
In Gregor Mussler 's group, we deal with molecular beam epitaxy of topological insulators and superconductors for quantum information.

Nanoelectronic devices

In Qing-Tai Zhao 's group, we are engaged in the research of nanoelectronic devices for advanced neuromorphic computing and quantum computers. For these applications, planar, as well as nanowire field-effect transistors (FETs) based on various group IV semiconductors and heterostructures are designed, fabricated, and characterized.

Semiconductor epitaxy and quantum optics

In Alexander Pawlis's team, we are interested in fabricating and studying nanostructured devices for optical quantum communications.
