Abstract

Carbon nanotubes are grown on Ni catalyst coated on soda-lime glass substrates using chemical vapor deposition of C₂H₂ gas at 550°C. Ni film is coated on the surface of Ag film using the electroplating method. Ni was etched by ammonia (NH₃) gas in order to form nanometer sized catalytic particles before carbon nanotube growth. Pd film is applied as a gas activator to decrease the growth temperature of carbon nanotubes. The carbon nanotubes grown on Ni catalyst particles showed a multiwalled structure with defective graphite sheets at the wall. The turn-on voltage was about 2.8 V/μm with an emission current density of 10 μA/cm², and the threshold voltage was about 4.0 V/μm with an emission current density of 10 mA/cm². The Fowler-Nordheim plot showed a good linear fit, indicating that the emission current of carbon nanotubes follows Fowler-Nordheim behavior. The calculated field enhancement factor was 2850.
