Fabrication of gold nanowires using self-organized porous alumina template

Highly ordered gold nanowire arrays have been prepared by low frequency electrodeposition from self-organized porous alumina templates. The porous alumina templates were fabricated using the two-step anodization process. The diameter of nanowire is 40 nm, which is dependent on the pores of the template membrane we prepared. The length of gold nanowires was determined by varying the operating time of electrodeposition.
