We describe a new mechanism for the nucleation of carbon nanotubes which does not require an abrupt transition from pentagonal ring formation to exclusively hexagon formation. This mechanism, the spontaneous opening of double-layered graphitic patches, is quantitatively consistent with the recently discovered temperature dependence of the nanotube diameter.
