Controllably modulated asymmetrical photoresponse with a nonvolatile memory effect in a single CH3NH3PbI3 micro/nanowire for photorectifiers and photomemory

By clarifying electrode interface photoresponse of CH 3 NH 3 PbI 3 micro/nanowires, multifunction photorectifier and self-powered photodetector are achieved. Precise modulation of electrode interface states with voltage and illumination enables realization of nonvolatile photomemory.
