It is shown conclusively that individual carbon nanotube electron emitters indeed exhibit Fowler-Nordheim behavior and have a work function of 5.1±0.1 eV for the nanotubes under investigation, which had diameters of 1.4 and 4.9 nm 关键词: carbon nanotubes;electron field emission;work function;field emission properties;thin carbon nanotubes;electron emission measurements;Fowler-Nordheim behavior;work function;1.4 nm;4.9 nm;C
