Copper-based perovskites and perovskite-like halides: A review …
By further modifying the 2D perovskite through selective cutting, the 1D and 0D perovskite structures can be obtained [94]. Irrespective of the crystal size, the molecular-level properties of perovskites are contingent upon the degree of segregation between the metal halide species and the organic (or inorganic) cations [89]. The …
