Field emission behavior of the transferred substrate aligned array carbon nanotube films
A novel technology is explored, using which an aligned array carbon nanotube film (aacf) can be perfectly peeled off from itself growing substrate as well as transferred onto an aluminum tape substrate, being assembled a composite film together with the AI tape. The electrical conductance and the field emission behaviors have been tested for the composite films. Experimental results show that the composite film has electrical resistance between 10 ohm and 1127 ohm, which depends on thickness and quality of the sticky glue layer between the carbon nanotub (cnt) film and the AI substrate. F-N curve proves the electronic emission of the composite film is field emission. I-V measurement curves demonstrate that the composite film with good electrical conductance has better field emission behavior and that the turn-on field and threshold field of sample 1 are 1.1 V/um and 1.8 V/um respectively. The technology datum show the composite film can meet the requirements of the emission cathode in fiat panel displays.
