Abstract

Two-dimensional (2D) organic-inorganic hybrid perovskites are widely used in various optoelectronic devices due to their natural quantum well structure and unique optoelectronic properties. Compared with perovskite film materials, perovskite single crystals have fewer grain boundaries and lower defect density. They are ideal materials for studying the fundamental properties of perovskite. However, how to prepare large-sized 2D perovskite single crystals to facilitate their practical applications in photodetectors is still a challenge. Herein, we prepare large-sized and high-quality 2D Ruddlesden-Popper (C₆H₅CH₂CH₂NH₃)₂PbBr₄ perovskite single crystals via an anti-solvent vapor-assisted method and deeply study their optoelectronic properties with lateral photodetectors. The device has extremely low dark current (5.72 × 10^-11 A), big responsivity (5.78 mA W^-1), and high specific detectivity (2.90 ×10¹⁰ Jones). This provides new ideas for the development of efficient and stable perovskite photodetectors.
