Abstract:
This letter describes the fabrication of copper nanowires within a nanoporous anodic alumina oxide (AAO) layer by electrodeposition through an AAO template. The diameter of nanowires less than 100 nm is generally about 50 nm, which corresponds to the diameter of the nanopores, and can be controlled by the anodic oxidation voltage. Using the AAO with nanowires as the dielectric layer of the dielectric barrier discharge device enables a typical reduction in the breakdown and extinction voltage by about 12%–18%, and 22% at most, in the Neon pressure range of 10–90 kPa. The gas discharge intensity is also enhanced. The field emission property of the integrated nanowires is measured in a vacuum environment, and the resulting emission current density of 0.1 μA/cm2 at an electric field of 5.5 V/μm is three times larger than that of a device without nanowires. This indicates that the reduction in operating voltage is mainly due to additional electrons produced by the nanowires. Additionally, the resulting Fowler–Nordheim characteristic clearly demonstrates the field emission behavior of the copper nanowires.
