Cobalt deposition into a nanotemplate made of anodized aluminum alloys

Abstract

Well – ordered nanotemplates were obtained by anodisation of pure Al and Al-alloys in sulfuric acid. A bottom-up filling up of these templates with Co nanowires was investigated. The growth of cobalt nanowire arrays in the anodic aluminum oxide layers (AAO) was done under AC electrodeposition code. The optimal AC mode under Vp-p = 30 V was in the range of 150 – 200 Hz. The uniformity of pore filling can be achieved only for several micrometers of nanowires.
