Chemical transport reaction enables growth of pure and alloyed inorganic nanotubes with extremely low structural defect densities and exceptional length. The narrow nanotubes self-assemble into ropes by syntactic coalescence. The mechanical and thermal stability of WS 2 nanotubes are discussed and some possible applications are suggested.
The chemical transport reaction known as a standard method for growth of transition metal dichalcogenides, was found as a successful technique for synthesis of MoS 2 and WS 2 nanotubes with extremely low density of structural defects. While microtubes usually grow as single tubes, the nanotubes combine to build ropes formed by coaxial or side-by-side growth of primary nanotubes. The...
