Electron-phonon couplings inherent in polarons drive exciton dynamics in two-dimensional metal-halide perovskites
Félix Thouin, Ajay Ram Srimath Kandada, David A. Valverde-Chávez +6
We report on the exciton formation and relaxation dynamics following photocarrier injection in a single-layer two-dimensional lead-iodide perovskite. We probe the time evolution of…

Enhanced screening and spectral diversity in many-body elastic scattering of excitons in two-dimensional hybrid metal-halide perovskites
Félix Thouin, Daniele Cortecchia, Annamaria Petrozza +2
In two-dimensional hybrid organic-inorganic metal-halide perovskites, the intrinsic optical lineshape reflects multiple excitons with distinct binding energies, each dressed differ…
