Abstract

Researchers demonstrate a polarization-sensitive photodetector by the fabrication of 1D perovskite single-crystal arrays, with strict alignment, precise position, homogeneous size, and high crystallographic order, through a facile and high-efficiency solution-processing method. The nucleation site and growth direction of perovskite crystals are manipulated by a micropillar-structured template with asymmetric wettability. A ‘capillary trailing’ is generated at the lyophobic–lyophilic boundary, with regulated shape, position, fluid flow, and dewetting dynamics, leading to a highly controllable crystallization process and yielding 1D-structure growth along the [100] orientation.
