Abstract Quasi-2D halide perovskites are chemically synthesized realizations of quantum well stacks with giant exciton oscillator strengths, tunable emission spectra, and very large exciton binding energies. While these features render quasi-2D halide perovskites a promising platform for room-temperature…
Abstract Controlling exciton relaxation and energy conversion pathways via their coupling to photonic modes is a central task in cavity-mediated quantum materials research. In this context, the light-matter hybridization in optical cavities can lead to intriguing effects, such as modified carrier transport,…
Layered perovskites are an emergent class of materials, which feature extraordinarily large light–matter coupling, driven by excitons with binding energies significantly beyond the thermal energy at room‐temperature. In this work, widely tunable room‐temperature cavity exciton polaritons are demonstrated…
