Photon and charge management in low-dimensional semiconductors (F01)

• Subject Area: Physical Chemistry of Molecules, Liquids and Interfaces, Biophysical Chemistry
• Term: since 2025
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 538767711

Project F1 is dedicated to investigating quasiparticles consisting of more than an electron and a hole (biexcitons, trions) in low-dimensional semiconductor phases and at their interfaces. Charge transfer between two solids or between a solid and an adsorbed molecule may be associated with phenomena such as triplet fusion, which allow for fundamentally new ways to harvest solar energy. These phenomena will be characterized by one-dimensional and two-dimensional time-resolved ultrafast spectroscopy in the optical and vibrational regimes, as well as by Raman, Stark, and photoluminescence spectroscopies in the steady state.
