Abstract :
A local heating chemical vapor deposition method is used to synthesize carbon nanotubes onto a metal substrate. Compared with normal thermal chemical vapor deposition, this method can provide faster growth rate, more nodes can be formed onto the carbon nanotubes, and emission sites can be increased largely. A maximum current over 100 mA was obtained from carbon nanotubes emitter layer with emission area is about 0.7 cm2. This method provides an effective way to fabricate carbon nanotubes into a vacuum electronic device to realize large current emission from a cold cathode instead of a thermionic cathode.
