Abstract

Over the past few years, lead halide perovskites (LHPs) in the form of single crystals (SCs) have been intensively investigated for photodetection applications. Methylhydrazinium (MHy) is a new type of organic cation that can form either 2D or 3D halide perovskite structures. Here, we study single crystals MHy₂PbI₄ (2D), MHy₂PbBr₄ (2D), MHyPbBr₃ (3D), and mixed-cation MA_0.725MHy_0.275PbBr₃ to determine for the first time how dimensionality and composition affect the photodetection properties of photoconductor-type photodetectors fabricated using this class of solids. The results provide a reference for researchers working in the same domain by revealing the relationship between different types and structures of LHPs and their optoelectronic properties, which is crucial for the further advancement of LHP-based optoelectronic devices.
