| Abstract: | A fundamental thermodynamic model of formation of catalyst clusters for growing carbon nanotubes has been developed and model
predictions have been compared with the experimental data. An expression for the size distribution function of clusters, depending
on the conditions of their formation, is obtained. It is shown that surface tension plays an important role in the cluster
formation. The surface tension coefficient for iron clusters at 950°C is determined. |
