| 发明名称 | Carbon nanotube field emitter | ||
| 摘要 | A carbon nanotube field emitter is disclosed. The carbon nanotube field emitter includes an emission portion and a supporting portion. The emission portion and the supporting portion are configured as one piece to form a roll structure. The emission portion includes a first rolled carbon nanotube layer, which includes a number of carbon nanotubes. The supporting portion includes a rolled composite layer, which includes at least one second rolled carbon nanotube layer and a rolled metal layer stacked with each other. Another carbon nanotube field emitter with a number of separated emission tips on the emission portion is also disclosed. | ||
