Self-Hybridized Polaritonic Emission from Layered Perovskites [PDF]

Nano Letters, 2021
Light-matter coupling in excitonic materials has been the subject of intense investigation due to emergence of new excitonic materials. Two-dimensional layered hybrid organic/inorganic perovskites (2D HOIPs) support strongly bound excitons at room-temperatures with some of the highest oscillator strengths and electric loss tangents among the known ...

Scaling law for excitons in 2D perovskite quantum wells

Nature Communications, 2018
Hybrid 2D layered perovskites are solution-processed quantum wells whose optoelectronic properties are tunable by varying the thickness of the inorganic slab. Here Blancon et al.

Exciton diffusion in two-dimensional metal-halide perovskites

Nature Communications, 2020
The so-called two-dimensional (2D) layered perovskites possess distinct optoelectronic properties from their 3D counterparts due to their reduced dimensionality. Here Seitz et al. investigate the exciton transport dynamics in 2D perovskites and highlight
