Abstract
The SrZrTiO3 (SZT) thin film prepared by sol-gel process for the insulator of resistive random-access memory (RRAM) is presented. Al was embedded in the SZT thin film to enhance the switching characteristics. Compared with the pure SZT thin-film RRAM, the RRAM with the embedded Al in SZT thin film demonstrated outstanding device parameter improvements, such as a resistance ratio higher than 107, lower operation voltage (VSET = −0.8 V and VRESET = 2.05 V), uniform film, and device stability of more than 105 s. The physical properties of the SZT thin film and the embedded-Al SZT thin-film RRAM devices were probed.
