Abstract

A fabrication technique is presented for depositing a metal film only on pointed tips by field-induced ion transfer (FIIT) in ambient atmosphere. The technique involves transferring metal ions dissolved in electrolyte solution only onto the pointed tip with electric field and it does not require any photolithographic process. To demonstrate the usefulness of the technique, carbon nanotubes are synthesized on the nickel film formed on a tungsten tip. The field emitter thus fabricated exhibits excellent emission characteristics. (© 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
