ABSTRACT
We have investigated the growth process of carbon nanotubes in carbon nanotubes as a function of anihilation temperature and duration. Raman spectroscopy is applied to characterize the produced DWCNTs. The RBM scales as l/d and renders the very narrow new inner CNTs easily detectable. We found a dramatic decrease of the fullerene concentration in the samples before the inner CNTs start to emerge. The growth of the new inner CNTs starts with the smallest diameter nanotubes, before it is uniformly extended to all possible diameters. © 2004 American Institute of Physics
