Abstract

A memristive switch device based on a-TSC:O ceramic film and a preparation method thereof, belonging to the technical field of optoelectronic devices. Based on the structure of traditional memristive switch devices, the present invention innovatively proposes "a-TSC:O thin film / a-SiO x The dielectric layer structure of "thin film" broadens the selection range of dielectric layer materials for memristive switching devices. Since the resistance switching properties of a‑TSC:O thin films can be adjusted in a wide range, and a‑SiO x The film is transparent and can provide an oxygen-vacancy electromigration channel, so that the a-TSC:O film has good resistive switching properties and can be used as a dielectric layer of a memristive switch device. At the same time, since the intrinsic a-TSC ceramic film has very good electrical conductivity and near-infrared transmittance, it can also be used as a top electrode material, and a near-infrared fully transparent memristive switch can be constructed together with the top electrode formed by a transparent conductive film. device. In addition, the present invention proposes that the memristive switch device has a simple preparation process, low cost, and high reliability, which is beneficial to realize large-scale production.
