The present invention relates to a field emission device comprising an anode and a cathode, wherein said cathode includes carbon nanotubes nanotubes which have been subjected to energy, plasma, chemical, or mechanical treatment. The present invention also relates to a field emission cathode comprising carbon nanotubes which have been subject to such treatment. A method for treating the carbon nanotubes and for creating a field emission cathode is also disclosed. A field emission display device containing carbon nanotube which have been subject to such treatment is further disclosed.
L'invention concerne un dispositif à émission de champ comprenant une anode et une cathode, la cathode contenant des nanotubes de carbone qui ont été soumis à un traitement énergétique, par plasma, chimique ou mécanique. L'invention concerne aussi une cathode à émission de champ contenant des nanotubes de carbone qui ont été soumis à un tel traitement. Elle concerne encore un procédé de traitement de nanotubes de carbone et de création de cathode à émission de champ. Elle concerne enfin un dispositif d'affichage à émission de champ contenant des nanotubes de carbone soumis à un tel traitement.
