PG - e1906185 LID - 10.1002/smll.201906185 [doi] AB - Metal halide perovskite has attracted enhanced interest for its diverse electronic and optoelectronic applications. However, the fabrication of micro- or nanoscale crystalline perovskite functional devices remains a great challenge due to the fragility, solvent, and heat sensitivity of perovskite crystals. Here, a strategy is proposed to fabricate electronic and optoelectronic devices by directly growing perovskite crystals on microscale metallic structures in liquid phase. The well-contacted perovskite/metal interfaces ensure these heterostructures serve as high-performance field effect transistors (FETs) and excellent photodetector devices. When serving as an FET, the on/off ratio is as large as 10(6) and the mobility reaches up to approximately 2.3 cm(2) V(-1) s(-1) . A photodetector is displayed with high photoconductive switching ratio of approximately 10(6) and short response time of approximately 4 ms. Furthermore, the photoconductive response is proved to be band-bending-assisted separation of photoexcited carriers at the Schottky barrier of the silver and p-type perovskites.
