Abstract

Abstract: In recent years, research on organic‐inorganic lead halide two‐dimensional (2D) perovskites has been blossoming. 2D perovskites have completely different layered structures from three‐dimensional perovskites, with interleaved organic and inorganic layers, leading to 2D perovskite materials being more stable and possessing anisotropic electrical transport. Meanwhile, 2D organic‐inorganic lead halide perovskite single crystals are receiving increasing attention because of their remarkable properties, such as long charge carrier lifetime, low defect density, and high photoluminescence quantum yield, increasing their potential for optoelectronic applications. Previously, a series of material systems based 2D perovskites single crystals has been synthesized and applied in various device applications. In this review, the preparation methods of organic‐inorganic lead halide 2D perovskite single crystals, the growth principles, their photoelectric properties and several device applications are discussed. Abstract : Recent progress in preparation and application of 2D perovskite single crystals is summarised. In this review, several preparation methods of 2D single crystals are discussed, including the underlying mechanism. Meanwhile, the applications of 2D organo‐inorganic perovskite single crystals in the fields of photodetectors, memristors and FETs are discussed. In addition, the challenges of 2D perovskite single crystals are also briefly summarized.
