Optical neuromorphic devices with metal halide perovskite materials

Abstract

The present disclosure relates to a method that includes reversibly switching a perovskite between a δ-phase and an α-phase, where, when the perovskite is substantially in the δ-phase, the perovskite is capable of absorbing light at a first wavelength and emitting light at a second wavelength and when the perovskite is substantially in the α-phase, the perovskite is capable of absorbing light at the first wavelength and emitting light at a third wavelength.
