Resistive Switching in Silver Iodide with Multi-Layer Graphene Electrodes

Memristors based on silver iodide (AgI), a solid-state electrolyte, with resistive switching are favored in artificial neural networks.In this study, high light transmittance of AgI was confirmed through the iodization of Ag using a vapor-phase iodization method.In addition, using transparent multi-layered graphene (MLG) as the electrode, an MLG/AgI/MLG structure was fabricated, with observations of its resistive memory switching and threshold switching characteristics measured to assess the possibility of application in a memory device and a selector, respectively.The findings here present the possibility of the use of AgI in highly transparent electronic devices for multiple uses.
