Abstract
Vertically aligned nickel nanowire arrays were successfully fabricated on silicon wafers by a chemical deposition process with the assistance of an extra magnetic field. The nanowire arrays are composed of polycrystal nickel nanowire typically about 300nm in diameter and a few of micrometer in length. The metal nickel was deposited and synchronously self-assembled into wires in the redox process. The nickel nanowires were aligned with their magnetic easy axes along the external magnetic line of force. A possible growth mechanism is also discussed. This method provides a simple and templet-free method to fabricate nanostructure and opens a new channel for building vertically aligned heterojunction device arrays..
