One-dimensional nanostructures such as nanowire and nanotube arrays have been intensively investigated due to its novel magnetic and optical properties depending on dimensional and size reduction. Especially in case of one-dimensional nanowire arrays with periodic structure, their applications will be extended to many devices for example biosensors, photonic crystals, and electro chemical devices. Therefore the fabrication of one-dimensional nanowire arrays with controlled morphologies and compositions becomes more important on a large scale.
Metal nanowire arrays with high aspect ratio have been prepared using a number of techniques including electron beam or focused ion beam (FIB) lithography, vapor-solid-liquid (VLS) growth process, and template synthetic method. Among these methods, template synthetic method is one of most promising one as increasing emphasis is placed on low cost, high throughput, and ease of production.
In this study, one-dimensional metal nanowire arrays composed of nickel, silver, and gold with single- or multi-segmented structures have been fabricated by electrochemical deposition method using AAO hard template. And these one-dimensional metal nanowire arrays will be estimated as highly active surface-enhanced Raman scattering (SERS) substrates.
