Cu nanowire arrays have been synthesized using potentiostatic electrodeposi
tion within the confined nanochannels of a porous anodic alumina membrane.
The Cu nanowire arrays and the individual nanowires have been characterized
using SEM, TEM, SAED, HREM and XRD. Investigation results reveal that the
Cu nanowire arrays having high wire packing densities are highly ordered ov
er large areas. The individual Cu nanowires (diameter similar to 60 nm) wer
e singlecrystal and found to be dense and continuous with uniform diameters
throughout their entire length. An optimum ECD condition (at lower overpot
entials) for the synthesis of singlecrystal Cu nanowires was also discussed
.
