Methylammonium lead iodide perovskite has attracted intensive interest forits diverse optoelectronic applications. However, most studies to date havebeen limited to bulk thin films that are difficult to implement for integrateddevice arrays because of their incompatibility with typical lithographyprocesses. We report the first patterned growth of regular arrays of perovskitemicroplate crystals for functional electronics and optoelectronics. We showthat large arrays of lead iodide microplates can be grown from an aqueoussolution through a seeded growth process and can be further intercalated withmethylammonium iodide to produce perovskite crystals. Structural and opticalcharacterizations demonstrate that the resulting materials display excellentcrystalline quality and optical properties. We further show that perovskitecrystals can be selectively grown on prepatterned electrode arrays to createindependently addressable photodetector arrays and functional field effecttransistors. The ability to grow perovskite microplates and to precisely placethem at specific locations offers a new material platform for the fundamentalinvestigation of the electronic and optical properties of perovskite materialsand opens a pathway for integrated electronic and optoelectronic systems.
