Polaron Vibronic Progression Shapes the Optical Response of 2D Perovskites Open
The optical response of 2D layered perovskites is composed of multiple equally‐spaced spectral features, often interpreted as phonon replicas, separated by an energy Δ ≃ 12 − 40 meV, depending upon the compound. Here the authors show that …
