摘要： A method for forming a carbon nanotube array includes the following steps: providing a smooth substrate (11); depositing a metal catalyst layer (21) on a surface of the substrate; heating the treated substrate to a predetermined temperature in flowing protective gas; and introducing a mixture of carbon source gas and protective gas for 5-30 minutes, thus forming a carbon nanotube array (61) extending from the substrate. When the mixture of carbon source gas and protective gas is introduced, a temperature differential greater than 50° C. between the catalyst and its surrounding environment is created by adjusting a flow rate of the carbon source gas. Further, a partial pressure of the carbon source gas is maintained lower than 20%, by adjusting a ratio of the flow rates of the carbon source gas and the protective gas. The carbon nanotubes formed in the carbon nanotube array are well bundled.

摘要： A field emission device includes a substrate (11) and a carbon nanotube array (12) formed thereon. Carbon nanotubes (120) of the carbon nanotube array are parallel to each other and cooperatively form a plurality of substantially rod-shaped lower portions (121, 121′) and a plurality of corresponding tapered tips (122, 122′) above the lower portions. Each lower portion and tapered tips have a plurality of carbon nanotubes. Distances between adjacent tips are approximately uniform, and are more than one micrometer. Preferably, the distance is in the range from 1 to 30 micrometers. The field emission device with this structure has reduced shielding between adjacent carbon nanotubes and has decreased threshold voltage required for field emission by the carbon nanotubes. The field emission device also contributes to an improved field emission concentration and efficiency.
