From: Cobalt and Nickel Nanopillars on Aluminium Substrates by Direct Current Electrodeposition Process
Slanted cross-section diagram describing the fabrication process of the metallic nanopillars.a NAAM template on aluminium substrate once the re-anodization process has finished;b A thin layer of metal is deposited at the pore bottom;c Rapid growth of metallic nanopillars inside the NAAM template;d Total filling with metal of the NAAM template pores;e Metal film formation on the NAAM surface;f Resulting array of Co and Ni nanopillars when the process is stopped at the end of the section 2 (S2) [Fig. 2(a) and (b)] and the NAAM substrate is removed
