چکیده انگلیسی
The field emissive carbon nanotubes (CNTs) with nickel tips were grown by a novel technique, double plasma hot filament chemical vapor deposition technique. Surface morphologies and structure of the sample were studied by a field emission scanning electron microscope, high resolution transmission electron microscope, Fourier transform infrared and Raman spectroscopy. Field emission (FE) of the sample was observed with a threshold field of ~ 3.4 V/μm. The high enhancement factor β derived from the slope of Fowler-Nordheim is attributed to the isolated nature of CNTs and nickel present at the CNT tip.
