A novel Ag/oxide-based threshold switching device with attractive features including ≈10 nonlinearity is developed. High-resolution transmission electron microscopic analysis of the nanoscale crosspoint device suggests that elongation of an Ag nanoparticle under voltage bias followed by spontaneous reformation of a more spherical shape after power off is responsible for the observed threshold switching.
研究人员开发出了一种基于 Ag/氧化物的新型阈值开关器件，具有 ≈10 的非线性度等引人注目的特性。对纳米级十字交叉器件的高分辨率透射电子显微镜分析表明，在电压偏置下 Ag 纳米颗粒的伸长，以及随后在断电后自发重新形成更球形的形状，是观察到的阈值开关的原因。
