Abstract

The kinetics of nanotube nucleation from a carbon-supersaturated nanodrop of a catalytic metal was considered. The problem of nucleation of the solid phase from a supersaturated melt was considered with allowance for the particular boundary conditions and the specificity of carbon structure. The solutions are obtained for the cases of extended and surface substrate nanopores, in which the carbon-supersaturated nanodrops are located. The threshold nucleation temperatures were determined for the single-and multiwall nanotubes and their bundles. The dependences of the nanotube size and the required supersaturation level on the temperature and nanodrop size are determined.
