BN-covered and insulated multiwalled semiconducting B-C-N nanotubes (NT), assembled in long ropes were produced and electrically tested. The atomic structure and chemical composition of ropes were analyzed by high-resolution transmission and energy-filtered electron microscopy. Individual ropes displayed perfect insulating performance of BN-rich outer layers and excellent field emission.
