Fabrication of nanoporous single crystal mica templates for electrochemical deposition of nanowire arrays

摘要

Nanopores with lateral dimensions as small as 33 nm have been fabricated by nuclear track etching in 5 μm thick, single crystal mica wafers. The nanopores have a diamond shape with their axes aligned with the crystal axes of mica as a result of anisotropic etching. Nickel nanowire arrays with a constant volume fraction have been fabricated by electrodeposition into the nanopores. The magnetic properties of the nickel nanowire arrays in the mica templates are reported.
