Plasmonic optoelectronic memristor with multifunction capability for neuromorphic vision. a) Schematic diagrams of human vision system and neuromorphic vision using the optoelectronic memristor. b) Device structure and cross‐sectional TEM image of the Ag—TiO₂ nanocomposite‐based memristor. c) High‐angle annular dark‐field imaging and elemental mapping images of the Ag—TiO₂ film. d) EDX scan analysis results for the Ag—TiO₂ film along the horizontal arrow indicated in part (c). e,f) HRTEM images of the Ag/TiO₂ heterostructure. The inset in (e) shows the statistical size distribution of the Ag NPs. g) Absorption spectra of the Ag—TiO₂ film and a pure TiO₂ film. The inset shows the differential spectrum.
