title: Anatomy of Ag/Hafnia-Based Selectors with 1010Nonlinearity.
abstract: A novel Ag/oxide-based threshold switching device with attractive features including ≈1010nonlinearity 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.
