BilayeredTwo-Dimensional Hybrid Perovskite with SwitchableDielectric Properties, Persistent Disorder, and Narrow-Band Emission

Abstract Two-dimensional (2D) multilayered lead halide perovskites have shown great potential for application in optoelectronics. Here, single crystals of 2D perovskite IPA2FAPb2Br7 (IPA = isopropylammonium, FA = formamidinium) were grown, and the phase transition mechanism, vibr...
