Abstract
Carbon nanotubes can be manufactured with a specific diameter but not with specific chiral vector, or conductance properties. A shift of the chemical potential can alter their conductance. Here we point out the possibility of obtaining a universal number of conducting channels for all same-radius tubes, regardless of their chirality, by a certain global shift of the chemical potential.
