label: single-walled carbon nanotube
label_lc: single-walled carbon nanotube
description: "A carbon nanotube consisting of a single graphene cylinder. Different kinds of single-walled carbon nanotube are distinguished by the indices (n,m) which describe the vector along which the graphene is rolled. The chiral angle is the angle between the vector and the origin and can take any value between 0 and 30degree."
