Controlling exciton migration in quasi-two-dimensional perovskite nanosheets (W05)

• Subject Area: Experimental Condensed Matter Physics ; Solid State and Surface Chemistry, Material Synthesis ; Optics, Quantum Optics and Physics of Atoms, Molecules and Plasmas ; Theoretical Chemistry: Electronic Structure, Dynamics, Simulation
• Term: since 2022
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 441234705

In project W05, we will study the exciton migration in quasi-two-dimensional perovskite nanosheets. Energy-landscape control will be achieved by colloidal synthesis of 2D Ruddlesden-Popper structures, which will be characterized in terms of crystallography and steady-state spectroscopy. A setup for time- and spatially resolved spectroscopy, including photoluminescence and transient absorption pump-probe experiments, will be built to study the spectrally and spatially resolved dynamics. Interpretation will be guided by atomistic density functional theory-based Hamiltonians and quantum dynamics methods with size-invariant scaling.
