ResumoUsing a solid electrolyte RbCu4Cl3I2 thin film and a controlled constant current electric field, the authors have directly fabricated macroscopic-long Cu nanowire bundles. Their structural characters have been described at different scales. The oxidation behavior of macroscopic-long Cu nanowire bundles containing thousands of straight and dendritic Cu nanowires was studied using x-ray photoelectron spectroscopy. Benefiting from the oxidized macroscopic-long Cu nanowire bundles, they have experimentally explored photoinduced conductivity in the bundle upon illumination with a 532nm laser beam, and observed that it can be regarded as a photoconductor with high sensitivity and fast response.
