Abstract—-In this work, aligned nickel nanowires have been fabricated by electrodeposition using anodic alumina oxide templates with 200 nm pore dimension. With this low cost deposition technique, a uniform filling of the membrane has been obtained with an height of the nanowires of 2 m. The field emission characteristics of the prepared NiNWs have been measured demonstrating, after a conditioning step, a stable behaviour that follows the Fowler-Nordheim law. A current density of 17,8 A/cm2 is obtained for an applied voltage of 570 V. A non-linear Fowler-Nordheim plot has been observed at high electric field that can be attributed to the non uniform field enhancement factor of the different nanowires.
