Abstract: We fabricated Ni nanowires into arrays of pores on ion track-etched polycarbonate membrane, using electrodeposition technique. The pores, which have cylindrical shapes with 6 micron depth and 30 nm width, filled by Ni atoms, fabricating arrays of Ni nanowires. The nanowires then characterised using scanning and transmission electron microscopy (SEM and TEM). Our results show that although the nanowires diameters are not perfectly uniform along the length, they are mostly continues. The samples then characterised using SEM and TEM. The selected area diffraction patterns of the similar wires from our previous work showed that the growth is polycrystalline, though the measured grain size was relatively large (Kazeminezhad and Nabiyouni, 2006).
