Abstract:
Formamidine-based hybrid perovskite is an excellent optoelectronic material; however, its intrinsic non-layered crystalline structure makes it hard to isolate the corresponding 2D counterparts. In this work, a unique liquid-epitaxy technique was introduced to grow micro-sized two-dimensional FAPbX3 perovskite sheets. Such ultrathin sheets exhibited excellent photo-induced carrier properties with high crystalline quality, as well as provided new opportunities for next-generation optoelectronic devices.
