Abstract
Optical chirality is intrinsically weak, and hard to tune in traditional bottom-up chiral perovskites. Here we realized all-dielectric halide perovskite chiral metasurfaces with a giant circular dichroism of 70% via high-throughput screening. Combining the giant optical chirality, unique light emission property and simple low-temperature solution processing technique, perovskite chiral metasurface paves the way towards real application in chiroptoelectronic and chiro-spintronic devices.
