Abstract :
The effect of Ar ion bombardment on field emission properties of CuO nanowires was investigated. A Kauffmann ion source was used to produce the Ar ion and bombard the CuO nanowires at the energy of 115, 215, and 415 eV. Non-crystallization and improvement of field emission properties of cupric oxide nanowires were observed. Lowest threshold field was obtained from nanowires after 215 eV Ar ion bombardment. The increase of field enhancement factor and decrease of work function may contribute to the enhanced field emission.
