On November 20th, 2025, Professor Alexey Chernikov visitied our group and besides exchanging knowledge with PIs and PhD students from Duisburg, he also gave a talk about “Optically detected transport in low-dimensional semiconductors” in terms of our seminar series.

Alexey Chernikov is a physicist at Technische Universität Dresden (TU Dresden), where he holds a W3‐professorship for Ultrafast Microscopy and Photonics. He earned his PhD at Philipps‑Universität Marburg in Germany, then worked as a Feodor-Lynen fellow at Columbia University in New York studying Coulomb phenomena in atomically thin two-dimensional systems. From 2016 to 2021 he led an Emmy-Noether research group at Universität Regensburg before joining TU Dresden in 2021.
In his research he investigates ultrafast processes of quasiparticles (such as excitons) in atomically thin nanocrystals, aiming to visualise and control their motion and interactions — with potential applications in lasers, sensors, solar cells and quantum technologies.

Exciton transport in two-dimensional semiconductors is governed by strong electron–hole correlations, vibrational interactions, spin–valley physics, and the rich excitonic landscape enabled by heterostructures and magnetic 2D materials. In his talk Alexey Chernikov highlighted how transient microscopy and diffusion studies reveal linear, nonlinear, and potentially quantum transport phenomena, as well as the coupling between exciton propagation and magnetic order.

Thank you, Alexey Chernikov, for your time and an interesting and entertaining talk!
