    • This invention relates to a method of fabricating a field emission device (FED) by using a carbon composite film, the composite film providing a field emission layer which consists of fine carbon-metal grains and/or carbon nanotubes, so that (a) a threshold voltage required for emitting electrons from the field emission device can be lowered significantly; (b) a stable electron beam of the field emission display device can be increased; and, (c) emission Uniformity and emission spot density can be greatly improved. The fabrication method involves preparing a metal-carbon composite film on a suitable substrate using an appropriate deposition technique. The carbon composite film is then thermally treated post-deposition, so as to form nano-particles and/or nanotubes in the film. Post-treatment of the composite film may involve annealing or plasma etching using hydrogen or hydrocarbon gas to reduce the electron emission barrier. During deposition of the metal-carbon composite film, the composition of the metal content in the film can be tuned to control the field emission properties of the field emission component.
    • 本发明涉及通过使用碳复合膜制造场发射器件(FED)的方法,该复合膜提供由细碳 - 金属颗粒和/或碳纳米管组成的场发射层,使得(a) 可以显着降低从场发射装置发射电子所需的阈值电压; (b)可以增加场致发射显示装置的稳定电子束; (c)排放均匀度和排放点密度可大大提高。 制造方法包括使用适当的沉积技术在合适的基底上制备金属 - 碳复合膜。 然后将碳复合膜在沉积后进行热处理,以便在膜中形成纳米颗粒和/或纳米管。 复合膜的后处理可以包括使用氢气或烃气体的退火或等离子体蚀刻以减少电子发射势垒。 在沉积金属 - 碳复合膜期间,可以调节膜中金属含量的组成以控制场致发射组分的场发射特性。
