WebJan 1, 1998 · The chiral vector thus forms the circumference of the nanotube’s circular cross-section, and different values of n and m lead to different nanotube structures (figure 1b). Armchair nanotubes are … Instead of the type (n,m), the structure of a carbon nanotube can be specified by giving the length of the vector w (that is, the circumference of the nanotube), and the angle α between the directions of u and w, may range from 0 (inclusive) to 60 degrees clockwise (exclusive). See more A carbon nanotube (CNT) is a tube made of carbon with diameters typically measured in nanometers. Single-wall carbon nanotubes (SWCNTs) are one of the allotropes of carbon, intermediate between See more the structure of the nanotube is not changed if the strip is rotated by 60 degrees clockwise around A1 before applying the … See more There is no consensus on some terms describing carbon nanotubes in scientific literature: both "-wall" and "-walled" are being used in combination with "single", "double", "triple", or "multi", and the letter C is often omitted in the abbreviation, for example, multi … See more Techniques have been developed to produce nanotubes in sizeable quantities, including arc discharge, laser ablation, chemical vapor deposition See more Basic details The structure of an ideal (infinitely long) single-walled carbon nanotube is that of a regular hexagonal lattice drawn on an infinite See more Narrowest examples If n and m are too small, the structure described by the pair (n,m) will describe a molecule that … See more Many properties of single-walled carbon nanotubes depend significantly on the (n,m) type, and this dependence is non-monotonic (see Kataura plot). In particular, the See more WebThe structure of a carbon nanotube is formed by a layer of carbon atoms that are bonded together in a hexagonal (honeycomb) mesh.
