ABSTRACT:
A field effect electron emitting apparatus is prepared by depositing a plurality of nano-wires216onto a substrate200having a cathode layer214. The deposition occurs by suspending the nano-wires216in a plating solution, and plating the substrate with a metal layer202, thereby entrapping the nano-wires. The nano-wires216are composed of an electrically-conductive magnetic material, and the deposition process is carried out in the presence of a magnetic field perpendicular to the substrate200so that the nano-wires216are aligned by the field.
