SYNTHESIS AND CHARACTERIZATION OF ELECTRODEPOSITED NICKEL NANOWIRES

One-dimensional nanostructures have attracted considerable attention due to their potential applications in a new generation of nanodevices. The template synthesis method has played an important role in the fabrication of many kinds of nanowires and nanotubes, for their interesting and useful features. Nanowires are expected to play an important role in future electronic and in electromechanical systems. When the nanowire diameter is of the same order as the charge carrier wavelength, quantum confinement effects shift energy states and the properties of nanowires strongly depend on size, shape and structure. We have studied the Ni nanowire electrodeposited in nanoporous anodic alumina membrane from a sulfate electrolyte containing 270 g/l NiSO4 center dot 7H(2)O, 40 g/l NiCl2 center dot H2O and 40 g/l H3BO3. The particle size was determined by AFM and SEM and the samples were characterized using XRD and EDX.
