- Abstract
The paper analyzes the analogy of single-crystal growth processes in directional solidification from a liquid melt and the synthesis of carbon nanotubes (CNTs) using CVD method. It was concluded that the cause of the curved morphology of the tubes is the non-uniform in time flow of carbon through the catalytic centers (CCs) to the places of their growth. The features of the dissociation processes kinetics on the CCs surface and the diffusion inside of them are analyzed in cases where the CCs are in different phase states. The features of the "root" and "caps" growth of the tubes in the same technological conditions are considered. The plasma component of the working gas has been shown to play an important role in formation of a carbon–polymer coating on substrates and the appearance of a substructure on CNTs surfaces
