A simple and efficient combined AC-DC electrodeposition method for fabrication of highly ordered Au nanowires in AAO template

▸ The Au nanowire is fabricated in AAO template with barrier layer by combined AC-DC electrodeposition method which is firstly used. ▸ The fabricated Au nanowires displayed uniform length and the range of current density is much larger comparing with single DC plating. ▸ The cyclic voltammetry result reveals that the cathodic peak was more negative after AC preplating. ▸ A new mechanism is proposed and the evidence comes from the TEM result of the two branched Au nanowires.
