Multi-walled carbon nanotubes modelling

A modeling process of multi-walled «Russian doll» and «scroll» carbon nanotubes is introduced in the article. Some geometry features, especially interval between layers, according to which the existence of nanotubes with any configuration is impossible, are discussed. Acquisition of atom coordinates in «Russian doll» nanotubes is considered. All restrictions and features of single-walled carbon nanotubes construction are taken into account.
