From: Modeling and characterization of stochastic resistive switching in single Ag2S nanowires
Resistive switching of a single Ag2S NW. (a) A nanomanipulator (Kleindiek Nanotechnik, GmbH) with a custom-made Pt/Ir 80–20 electrode contacting a tip of a single Ag NW exposed on a microscope slide with another tip submerged under Ag paint. (b) A microscopic image and IV characteristic of a single 20 \(\upmu\)m long Ag2S NW under a negative-positive-negative triangular-shaped voltage cycle. Each point correspond to a particular event that is described in the text of the manuscript. (c) IV characteristics of the same Ag2S NW as in (b) after it was shortened to 10 \(\upmu\)m. The arrows show direction of the voltage sweep. (d) Conducting (ON) state of the model of RS in a single Ag2S NW with scattered Ag nanocrystal inclusions and Ag2S-\(\beta\) nanobridges in Ag2S-\(\alpha\) phase (adapted from Xu et al. 24). (e) Non conducting (OFF) state of the model. All scale bars are 10 \(\upmu\)m long, unless specified.
