title = "Enhanced field emission of well-aligned ZnO nanowire arrays illuminated by UV",
abstract = "Vertical zinc oxide nanowires, used as electron emitters, were synthesized on ZnO:Ga/glass substrate by a vapor-liquid-solid process without a catalyst. The nanowires, 5 μm long and 50-250 nm in diameter, were grown with a preferred (0 0 2) orientation and a small XRD full-width at half-maximum intensity. Illumination of ZnO nanowires by UV improved their field emission attributes, reducing their turn-on electric field to 2.1 V/μm at a current density of l μA/cm2. This phenomenon is attributed to the generation of a large number of hole-electron pairs by UV illumination.",
