Hello - welcome to our research group!                        

In the Stier sub-group at the SNQS chair of WSI (Prof. J. J. Finley), we explore the properties of novel nanomaterials with a current focus on 2D semiconductors and van der Waals stacked hybrid structures. Specifically, we aim to understand the influence of dielectric, magnetic and/or topological environments on the electrical and optical properties of our structures.

We want to fundamentally understand such systems and to learn how to control and tailor their properties with a vision towards photonics, electronics, quantum technologies and energy harvesting.

To reach our goal, we pursue all stages from material preparation to characterization of electronic, optical and structural properties, as well as device fabrication and – of course - probing of device functionalities.

Because the energetic landscape in 2D materials is significantly different from conventional semiconductor materials, we sometimes use very large magnetic fields and very low temperatures for our studies – tools that allow us to test our devices in a regime where quantum effects occur.
