摘要
A new electrochemical method for forming single metal nanostructures (nanowires) is described. A standard track membrane with statistically distributed etched high-density channels is used as a template. A few track membranes are stacked in a multilayer sandwich and tightly pressed to each other and to a metal substrate-cathode. Metal is electrochemically deposited into the through etched channels of the track membranes. Since the probability of statistically distributed etched through channels in a sandwich of track membranes being butted together is rather low, etched channels with electrochemically deposited metal decrease in number in each subsequent track membrane, beginning with the substrate-cathode, until a single nanostructure is formed in the top track membrane.
