Direct high-resolution electron microscopy of BN nanotubes with hexagonal zigzag network

Hexagonal zigzag network of boron nitride (BN) nanotubes was investigated by high-resolution electron microscopy (HREM) and image processing. From the HREM image, lattice planes of {0 0 2} and hexagonal rings of BN nanotube were confirmed by comparing image simulation and nanostructure models. The present work indicated that arrangement of hexagonal rings of BN nanotubes could be confirmed by combination of HREM image analysis and simulation.
