Abstract

Polarization-sensitive perovskite photodetectors are realized by crystallographically aligning 1D perovskite arrays. High-quality inorganic perovskite single crystals with crystallographic order are fabricated by strictly manipulating the dewetting process of organic solution, yielding photodetectors with high photoresponsivity and fast response speed.
