Abstract
Halide perovskites, owing to their excellent characteristics, have demonstrated huge potential in next-generation optoelectronic applications. Creating perovskite heterostructures, featuring the spatial modulation of physical properties, is expected to further boost device performance and open up new realms; however, direct growth of spatially defined mixed-dimensional lateral heterostructures remains a significant challenge. Here, we present a one-pot solution synthesis of two-three-dimensional (2D-3D) perovskite crystalline lateral heterostructures, leveraging their different temperature-dependent solubilities. A series of lateral heterostructures is demonstrated with well-defined interfaces and clear structural and optical modulations. Benefiting from the built-in field that effectively suppresses the dark current and separates the photogenerated carriers, the proof-of-concept photodetectors yield a low dark current less than 0.01 nA and a champion detectivity exceeding 1013 Jones. The general, facile synthesis of diverse mixed-dimensional perovskite lateral heterostructures provides a versatile hybrid material platform for exploring unique physics and affords new opportunities for advanced perovskite electronics.
