Carbon nanotubes have many structures, differing in length, thickness, type of helicity, and number of layers. Although they are formed from essentially the same graphite sheet, their electrical characteristics differ depending on these variations, acting either as metals or semiconductors.  4, record 1, English, - carbon%20nanotube

Carbon nanotubes are unique nanostructures with remarkable electronic and mechanical properties. A carbon nanotube is an extremely small, thin, and hollow cylinder structure formed by rolling seamlessly a single layer of graphite. As other properties have been discovered, particularly strength, interest has grown in potential applications for example, in nanometre-sized electronics or to strengthen polymer materials.  5, record 1, English, - carbon%20nanotube

nanotube: Since studies seem to concentrate on carbon (i.e. graphene) nanotubes, this term is often used as a synonym of "carbon nanotube," but keep in mind that there are less common non-carbon nanotubes.  7, record 1, English, - carbon%20nanotube

Un nanotube de carbone est composé d'un ou de plusieurs feuillets de graphène (c'est-à-dire un plan graphitique dans lequel les atomes de carbone sont organisés selon un réseau hexagonal à l'image d'un nid d'abeilles) enroulés, suivant un rayon de courbure nanométrique, de façon à former une structure cylindrique.  4, record 1, French, - nanotube%20de%20carbone

nanotube : Ce terme est souvent utilisé comme synonyme, car les nanotubes de carbone (c.-à-d. de graphène) sont les plus couramment étudiés (ou utilisés). Cela dit, il faut savoir qu'il existe des nanotubes qui ne sont pas à base de carbone.  5, record 1, French, - nanotube%20de%20carbone
