Abstract

We report on the fabrication of nonvolatile organic memory devices that utilize silver-copper (Ag-Cu) nanoparticles as charge storage elements. Herein, Ag-Cu nanoparticles of an average size of 12 nm were impeded between thin layers of polymers: poly(methyl methacrylate) (PMMA), and poly-vinyl-alcohol/poly acrylamide co-acrylic acid with glycerol ionic liquid (PVA-PAA-glycerol). PMMA acts as a dielectric layer, while our newly developed PVA-PAA-glycerol polymer acts as a semiconducting layer. The conductivity of PVA-PAA-glycerol could be controlled conductivity by adjusting the percentage of glycerol. Aluminum films of desired thickness were produced by thermal evaporation and used as electrical electrodes. Capacitance-voltage (C(V)) measurements of the fabricated devices revealed hysteresis with a 10 V window. This is an indication of charge storage within Ag-Cu nanoparticles.
