A carbon nanotube manufacturing apparatus (1000, 2000, 3000) comprises an ionizing means (e.g. a negative ion generator (10)) for ionizing a vapor of a certain carbon-containing compound, an electric field generating means (e.g. a direct-current power supply (21), a cathode (22) and an anode (23)) for generating an electric field and a heating means (e.g. a high-frequency heater (30)) for heating a growth substrate (50, 55) disposed within the electric field generated by the electric field generating means. A carbon nanotube manufacturing method in which an ionized vapor of the carbon-containing compound is passed through the electric field and brought into contact with the heated growth substrate, so that a carbon nanotube (4) is orientationally grown on the growth substrate is adopted.
L'invention concerne un dispositif (1000, 2000, 3000) permettant de fabriquer des nanotubes de carbone, qui comprend des moyens ionisants (p. ex. générateur d'ions négatifs (10)) pour ioniser la vapeur d'un certain composé carboné ; des moyens de production de champ électrique (p. ex. alimentation (21) en courant continu), cathode (22) et anode (23)) pour produire un champ électrique ; et des moyens de chauffe (p. ex. élément chauffant (30) haute fréquence) pour chauffer un substrat de croissance (50, 55) placé dans le champ électrique produit par les moyens de production de champ électrique. L'invention concerne aussi un procédé de fabrication de nanotubes de carbone, dans lequel la vapeur ionisée du composé carboné passe à travers le champ électrique et est mise en contact avec le substrat de croissance chauffé, de manière à faire croître un nanotube (4) de carbone dans une certaine orientation sur ledit substrat.
