Field emission cathode structure |
摘要 |
A field emission cathode structure includes a first carbon nanotube structure including a plurality of first carbon nanotubes, and a second carbon nanotube structure located on the surface of the first carbon nanotube structure. The second carbon nanotube structure includes a plurality of second carbon nanotubes substantially perpendicular to the first carbon nanotubes structure. The second carbon nanotube structure includes a peak. The heights of the second carbon nanotubes at the peak are tallest. The heights of the carbon second carbon nanotubes gradually decrease along the direction away from the peak. A method for fabricating the field emission cathode structure is also presented. |
