From natural biomaterials to environment-friendly and sustainable nonvolatile memory device

Abstract The memory device based on biomaterials is of great value in future applications because the biomaterials are environment-friendly, renewable and pollution-free. In this work, natural biomaterials, which were firstly extracted and processed from orange peel, were used as an active layer for fabricating an environment-friendly and sustainable nonvolatile memory device with Ag/Orange peel/FTO sandwich structure. An obvious memory behavior with reproducible bipolar resistive switching memory performance and large resistive storage window has been observed. This work reveals that the orange peel is a promising material for fabricating an environment-friendly and sustainable memory device in nonvolatile memory applications.
