Aligned carbon nanotube films: production and optical and electronic properties
Walt A. deHeer,Wolfgang Bacsa,A. Châtelain,T. Gerfin,R. Humphrey-Baker,László Forró,Daniel Ugarte +6 more
TL;DR: A method has been developed to produce thin films of aligned carbon nanotubes, which can be aligned either parallel or perpendicular to the surface, as verified by scanning electron microscopy.

Nanometre-size tubes of carbon
TL;DR: In this paper, the authors review the present state of understanding of the structure, growth and properties of nanometre-size tubes of carbon and present promising areas of future applications, for example as tiny field-emitting devices, micro-electrodes, nanoprobes and hydrogen storage material.

Helical microtubules of graphitic carbon
TL;DR: Iijima et al. as mentioned in this paper reported the preparation of a new type of finite carbon structure consisting of needle-like tubes, which were produced using an arc-discharge evaporation method similar to that used for fullerene synthesis.
Journal ArticleDOI
New one-dimensional conductors: Graphitic microtubules.
TL;DR: It is predicted that carbon microtubules exhibit striking variations in electronic transport, from metallic to semiconducting with narrow and moderate band gaps, depending on the diameter of the tubule and on the degree of helical arrangement of the carbon hexagons.
Journal ArticleDOI
Pentagons, heptagons and negative curvature in graphite microtubule growth
TL;DR: In this article, the authors present images from transmission electron microscopy of a further kind of growth morphology, in which cone-like growth is transformed into cylindrical growth by the incorporation of a defect that induces negative curvature.
Journal ArticleDOI
Formation of Carbon Nanofibers
Morinobu Endo,Harold W. Kroto +1 more
TL;DR: In this article, it is proposed that these structures may be giant fullerenes which have grown by direct insertion into the graphitic network of smaller carbon species accreted from the vapor phase.

Relation between Dislocations and Disclinations
TL;DR: The theory of disclinations contains the equation ∂iαij + ejmnθmn = 0, where α and θ are the dislocation and disclination density tensors, respectively.
