Highly reproducible bipolar resistance switching was recently demonstrated in a composite material of Pt nanoparticles dispersed in silicon dioxide. Here, we examine the electrical performance and scalability of this system and demonstrate devices with ultrafast (<100 ps) switching, long state retention (no measurable relaxation after 6 months), and high endurance (>3 × 10(7) cycles). A possible switching mechanism based on ion motion in the film is discussed based on these observations.
最近,在 Pt 纳米粒子分散在二氧化硅中的复合材料中,人们展示了具有高度可重现性的双极性电阻开关性能。在这里,我们研究了该系统的电性能和可扩展性,并展示了具有超快(<100 ps)开关、长状态保持(6 个月后无明显弛豫)和高耐久性(>3×10(7)次循环)的器件。基于这些观察结果,讨论了基于膜中离子运动的可能开关机制。
