Each species of an atom is called a n
WebThe helical structure of carbon nanotubes is described by the chiral vector, C = n a 1 + m a 2, represented by (n, m), where n and m are integers and a 1 and a 2 are non-orthogonal basis vectors. There are three basic types of carbon nanotubes depending on the chiral vector, and these are armchair m = n , zigzag m = 0 and chiral with 0 < m < n .
