Abstract :
We modify multi-wall carbon nanotubes (MWCNTs) by plasma treatment with N2 and Ar for varying durations and measure their field emission characteristics. The N2 treated MWCNTs showed significant improvement in field emission properties, while the Ar treated MWCNTs displayed poorer field emission characteristics compared to untreated MWCNTs. X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), Raman spectroscopy and work function measurements are used to investigate the field emission mechanisms after plasma treatments.
