The present invention is directed to a nanotube coated with diamond or diamond- like carbon, a field emitter cathode comprising same, and a field emitter comprising the cathode. It is also directed to a method of preventing the evaporation of carbon from a field emitter comprising a cathode comprised of nanotubes by coating the nanotube with diamond or diamond-like carbon. In another aspect, the present invention is directed to a method of preventing the evaporation of carbon from an electron field emitter comprising a cathode comprised of nanotubes, which method comprises coating the nanotubes with diamond or diamond-like carbon.
La présente invention concerne un nanotube revêtu de diamant ou d'un carbone de type diamant, une cathode d'émetteur de champ le comprenant ainsi qu'un émetteur de champ contenant la cathode. L'invention concerne également un procédé de prévention de l'évaporation de carbone à partir d'un émetteur de champ comprenant une cathode composée de nanotubes par revêtement du nanotube avec du diamant ou du carbone de type diamant. Dans un autre aspect, la présente invention concerne un procédé de prévention de l'évaporation de carbone à partir d'un émetteur de champ électronique comprenant une cathode composée de nanotubes, lequel procédé consiste à revêtir les nanotubes de diamant ou de carbone de type diamant.
