Prof. Dr. Jannika Lauth

Eberhard Karls UNiversity Tübingen
The research of Jannika Lauth focuses on the synthesis and characterization of ultrathin colloidal 2D semiconductors for optoelectronic applications. Using wet-chemical methods, her group produces mono- and few-layer nanosheets with tunable properties arising from quantum confinement. These materials exhibit strong excitonic effects and efficient charge carrier dynamics, making them suitable for devices such as LEDs, photodetectors, and solar cells. The group also develops colloidal 2D semiconductor inks that can be processed easily onto different surfaces, substrates and cover a broad spectral range from UV–Vis to NIR/SWIR. Their work is complemented by ultrafast transient absorption spectroscopy to study charge carrier dynamics and optoelectronic properties in real time.
