“…Lead-halide perovskites (LHPs) are a promising class of low-cost, highperformance semiconductors, that have great prospects in solar cells, solidstate lighting, lasers, and photocatalysis due to their excellent optoelectronic properties. [1][2][3][4][5][6][7][8][9][10] Nonetheless, long-term stability is still a challenge, accompanied by a decrease in the photovoltaic conversion efficiency of LHPs during their real applications. In previous studies on improving the stability of LHP devices, surface/interface engineering was considered an effective strategy to maintain the intrinsic stability of lattice structures and even suppress phase transition.…”

Ruddlesden–Popper (RP) interface with defined stacking structure will fundamentally influence the optoelectronic performances of lead‐halide perovskite (LHP) materials and devices. However, it remains challenging to observe the atomic local structures in LHPs, especially for multi‐dimensional RP interface hidden inside the nanocrystal. In this work, the advantages of two imaging modes in scanning transmission electron microscopy (STEM), including high‐angle annular dark field (HAADF) and integrated differential phase contrast (iDPC) STEM, are successfully combined to study the bulk and local structures of inorganic and organic/inorganic hybrid LHP nanocrystals. Then, the multi‐dimensional RP interfaces in these LHPs are atomically resolved with clear gap and blurred transition region, respectively. In particular, the complex interface by the RP stacking in 3D directions can be analyzed in 2D projected image. Finally, the phase transition, ion missing, and electronic structures related to this interface are investigated. These results provide real‐space evidence for observing and analyzing atomic multi‐dimensional RP interfaces, which may help to better understand the structure‐property relation of LHPs, especially their complex local structures.
