Resumen:
Vertically aligned single-walled carbon nanotube SWNT forest was studied by using angular-dependent C K-edge x-ray absorption near edge structure XANES with linearly polarized x-ray beam. The XANES analysis found a crust of entangled nanotubes on top of the forest formed at the first stage of the forest growth, which shapes the morphology of the entire forest and constricts the nanotubes to grow to the same length. It indicates that this type of SWNT forest has a different growth mechanism from the multiwalled carbon nanotube forest.
