Abstract :
In this paper, the effects of catalyst film thickness on the field emission currents and the emission stability of carbon nanotubes (CNTs) are presented. The CNTs are grown on Ni catalyst films of different thickness (20 nm, 50 nm, 70 nm) by chemical vapor deposition (CVD). Results show that the CNTs grown on 20 nm catalyst films have a poorer field emission and poorer emission stability than those of 50 and 70 nm catalyst films
