The Scheme of the Nucleation of [6,6] CNT via Zipping Mechanism

From top to bottom, the scheme of the NT nucleation process:

Zipping of the edge of double-layer of graphite results in a sleeve structure formation. The radius of the sleeve (NT precursor) grows until the preexisting defect of the graphite sheet stops the blowing. Then a strait opens and the [6,6] nanotube detaches from the graphite "main-land"

Bottom part of the figure shows the calculated Raman-active phonon mode of [6,6] NT. Red arrows depict atomic vibration amplitudes.
