Observation of elastic heterogeneity and phase evolution in 2D layered perovskites using coherent acoustic phonons

Two-dimensional (2D) organic–inorganic perovskites have shown interesting optical properties due to the natural quantum-well structures. The repetition of soft organic and hard inorganic intercalations also renders 2D perovskites rich phonon dynamics. Here, we investigated the coherent acoustic phon...
