Hybrid Improper Ferroelectricity and Moir\'e Superlattices-induced Exciton Quantization in Layered 2D Halide Perovskite
Hybrid improper ferroelectricity in (PA)2FAPb2I7 induces ~5.17° layer misalignment creating a moiré superlattice that quantizes excitons into an equidistant photoluminescence ladder at 123 K.
