Influence of adsorption small molecules atrazine on nonvolatile resistive switching behavior in Co–Al layered double hydroxide films

Co–Al-layered double hydroxides (LDHs) thin films were prepared by drop-casting process on ITO-coated glass substrates. And then the small molecule atrazine was adsorbed Co–Al LDHs film impregnation method. Current–voltage characteristics revealed nonvolatile resistive switching in films. The Influence of adsorption molecules behavior has been investigated. By varying content films, device could be adjusted a controlled way. Entirely different characteristic, such as write-once read-many-times memory effect and rewritable are discriminable current–voltage curves.
