Ionic Transport Triggered by Asymmetric Illumination on 2D Nano-Membrane.

ABSTRACT: Ionic transport and ion sieving are important in the field of separation science and engineering. Based on the rapid development of nanomaterials and nano-devices, more and more phenomena occur on the nanoscale devices in the field of thermology, optics, mechanics, etc. Recently, we experimentally observed a novel ion transport phenomenon in nanostructured graphene oxide membrane (GOM) under asymmetric illumination. We first build a light-induced carriers' diffusion model based on our previous experimental results. This model can reveal the light-induced ion transport mechanism and predict the carriers' diffusion behavior under different operational situations and material characters. The voltage difference increases with the rise of illuminate asymmetry, photoresponsivity, recombination c
