The chemical reactionbetween Ag nanoparticles (Ag NPs) and 7,7′,8,8′-tetracycanoquinodimethane (TCNQ) microparticles (MPs) in aqueous solution to form Ag-NP-decorated Ag–TCNQ nanowires is reported. The reaction between Ag NPs and TCNQ MPs indicate three stages: the aggregation of NPs and MPs, diffusion and reaction between NPs and MPs, and formation of Ag–TCNQ nanowires. The as-synthesized semiconducting nanowires show good performance in nonvolatile memory devices with multiple write-read-erase-read (WRER) cycles at room temperature in air.
