(FR) DISPOSITIF D’ENREGISTREMENT DE DONNEES COMPORTANT DES NANOTUBES DE CARBONE INCLINES ET PROCEDE DE FABRICATION
Abstract
(EN)
The device for recording data comprises a network of carbon nanotubes (9) formed on a planar substrate (10) and forming microdots which cooperate with a storage medium (11) which is substantially planar. The carbon nanotubes (9) are initially inclined at a predetermined angle ranging from 5° to 40°, in relation to the plane of the substrate (10). The naontubes 9 bend when they come into contact with the storage medium (11), parallel to the substrate (10). Preferably, the substrate (10) comprises a relief structure which is used to provide support for the free extremities of the nanotubes (9).
(FR)
Le dispositif d'enregistrement de données comporte un réseau de nanotubes (9) de carbone, formés sur un substrat (10) plan et constituant des micro pointes coopérant avec un support de mémoire (11) sensiblement plan. Les nanotubes (9) de carbone sont initialement inclinés d'un angle prédéterminé, compris entre 5° et 40°, par rapport au plan du substrat (10). Les nanotubes 9 fléchissent lorsqu'ils viennent en contact avec le support de mémoire (11), parallèle au substrat (10). Le substrat (10) comporte, de préférence, une structure en relief, destinée à servir d'appui aux extrémités libres des nanotubes (9).
