Abstract

The theoretical analysis of the electronic structure of a single pentagon-heptagon-based connection between the armchair (4.4) and zigzag type (7.0) half-nanotubes, consisting of 131 carbon atoms, as well as of pure carbon nanotubes of the armchair type (4.4) of carbon 128 atoms and zigzag type (7.0) of 126 carbon atoms is given. It was shown that in the case of bent carbon nanotubes under study, the metal–semiconductor transition does not occur.

Key words: carbon nanotubes, electronic structure, Green functions, energy spectrum, density of electronic states.
