Monodisperse metal nanowire arrays on Si by integration of template synthesis with silicon technology

Abstract

Thin films of monodomain porous alumina with 2 µm thickness and adjustable monodisperse pore diameter are obtained via anodization of nanoimprinted Al evaporated on a Si wafer. By using these templates, hexagonally arranged monodisperse silver nanowires on Si are prepared by electrochemical deposition with a commercially available bath. In addition, free standing Ag nanowires on Si are prepared by selective dissolution of the alumina matrix.
