WebJan 1, 2024 · Carbon nanotubes (CNTs) are a kind of tubular structure typically having nanometer-scaled diameter and micrometer-scaled length. Because of their tiny … The structure of an ideal (infinitely long) single-walled carbon nanotube is that of a regular hexagonal lattice drawn on an infinite cylindrical surface, whose vertices are the positions of the carbon atoms. Since the length of the carbon-carbon bonds is fairly fixed, there are constraints on the diameter of the cylinder and the arrangement of the atoms on it.
