摘要：
Field emission from (i) as-grown multiwall nanotubes (MWNTS), (ii) purified MWNTs and (iii) purified single-wall nanotubes (SWNTs) was investigated by field emission microscopy(FEM). As an application of nanotube held emitters, we manufactured cathode ray tube (CRT) lighting-elements by replacing conventional thermionic cathodes with nanotube field emitters. Stable electron emission, high emission current with low electric field (similar to 10 mA/cm(2) at 1.5 V/mu m), and long life of the emitters were demonstrated.
