* Alkali ion-based interface-type memristors offer solutions with benefits such as self-rectifying resistive switching and reduced variation between devices and cycles.
* A new Pt/Na/TiO/Pt memristor was created, demonstrating stable performance and a reliable resistive switching mechanism, verified through theoretical simulations.
* The study developed a novel alkali ion self-rectifying memristor using a bottom electrode design, with Li metal creating an ion reservoir and Al doping improving retention capabilities.
* Optimized devices demonstrated impressive performance, including over 20 hours of retention at 125 °C and low variability in reliability tests, indicating strong potential for future applications.
