| Abstract
| - We describe a new synthetic approach to fabricate Ni/Cu nanocable arrays by co-depositing nickel and copperatoms into the pores of anodic alumina membranes and to fabricate Ni nanotube arrays by selectively etchingthe Cu cores from the Ni/Cu nanocable arrays. The formation of the Ni-shelled Ni/Cu nanocables is attributedto the Ni ions adsorbed on the pore walls by a chemical complexation through hydroxyl groups. By varyingelectrodepositon parameters in this technique, we can control the lengths of nanocables and nanotubes, theshell thickness of the nanocables, and the wall thickness and surface morphology of the nanotubes.
