Bolt‐and‐Nut Pairs Made from Carbon Nanotubes with Artificial Defects

Abstract

Structures of double‐wall carbon nanotubes (DWNTs) with atomic scale defects that can operate as bolt‐and‐nut pair are analyzed. The relative thread depth for such bolt‐and‐nut pair is calculated for various types of defects in inner and outer walls of (4,6)@(12,8) and (8,2)@(16,4) DWNTs. It is found that a type of defect determines only the absolute thread depth but weakly influences on the relative thread depth. Possibility of producing of the DWNT (which can operate as bolt‐and‐nut pair) by self‐organization is proposed.
