Abstract :
The carbon nanotube film is grown by low press chemical vapor deposit (LPCVD) method after catalyst grains are introduced with ferro hydroxid sol. The variation of the concentration of catalyst grains versus the surface morphology of carbon nanotube film has been studied. When the distance between two nanotubes is from 200 nm to 500 nm, the threshold electric voltage is around 95 V for the best result in experiment. The electric field and the emission current of the top of carbon nanotube array have been computed using finite element analysis (software ANSYS 8.0), the results are matched with the experiment.
