"Boron Nitride Nanotubes: Recent Breakthroughs and Challenges"

Presented by Dmitri Golberg, National Institute for Materials Science (NIMS), Tsukuba, Japan

Friday, October 12, 2007, 1:30 pm — CFN Conference Rm. A, Bldg. 735

Most recent breakthroughs in preparation, structural analysis, functionalization and property measurements of multi-walled Boron Nitride nanotubes (BNNTs) at NIMS, Japan, are highlighted. The effects of bending deformation on the electrical response of individual multiwalled BNNTs under manipulation and electrical probing inside a high-resolution transmission electron microscope (HRTEM) are demonstrated. These effects include the deformation-driven electrical transport and first experimental signs of piezoelectricity in deformed BNNTs. In addition, BNNT bending forces are directly measured inside HRTEM and real-time video-recording of unusual elastic kinking BNNT deformation is performed.
