A prototype field emission display device was fabricated using copper nanowires as emitters. The copper nanowires were grown by chemical vapor deposition without any catalyst or template, which were analyzed by electron microscopy to show a five‐fold twinned structure with a pentagonal pyramid tip. The electron diffraction pattern disclosed that the twin boundaries were mismatched irregularly. The anisotropic growth of the copper nanowires in gas phase could be attributed to the passivation of the {100} side planes by the phosphite molecules dissociated from the precursor. Field emission characteristics of the nanowires were measured.
