Controllable growth of centimeter-size 2D perovskite heterostructural single crystals for highly narrow dual-band photodetectors
This paper presents a novel solution-based synthesis method for growing centimeter-sized, high-quality 2D perovskite heterostructural single crystals with controllable junction depths, which enable the fabrication of highly stable photodetectors exhibiting extremely low dark current and tunable, ultra-narrow dual-band spectral responses.
