Abstract
Electron emissionmeasurements were conducted on individual carbon nanotubes. The nanotubes had a closed end and their surfaces were thoroughly cleaned. It is shown conclusively that individualcarbon 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 .Keywords
