Abstract

Nanoparticles (304, 705) are coated using thick-film techniques with a catalyst (202) to promote the growth of carbon nanotubes (410) thereon. In one example, alumina nanoparticles are coated with a copper catalyst. Such nanoparticles can be selectively deposited onto a substrate (206) to create a field emission cathode (702, 802), which can then be utilized within field emission devices (700).
