Deflected nanotubes: The constant bending of boron‐doped multiwalled carbon nanotubes (BCNTs; see picture) produces a weak backscattering of the electron transmission, which is due to the fact that the primary conduction in p‐doped nanotubes is switched to an “extra” energy level near the valence‐band edge and the electron‐hopping amplitude at bending 2p z orbitals no longer plays a crucial role in the conduction mechanism.
