- Title
Pentagons, heptagons and negative curvature in graphite microtubule growth.
- Authors
Iijima, S.; Ichihashi, T.
- Abstract
Describes the standard carbon-arc synthesis for fullerenes and the production of graphitic microtubules with helical structures. Presents images from transmission electron microscopy of a different kind of growth morphology, in which cone-like growth is transformed into cylindrical growth by the incorporation of a defect that induces negative curvature. Possible cause of the defect in the hexagonal network responsible for negative curvature; More.
