Materials in the C-B-N ternary system have extraordinary properties such as Diamond and cubic-
BN. Nanotubes (NTs) belonging to this system have also attracted a significant attention for
applications in nanoelectronics, medicine, energy systems, and reinforced-composites because of
their potential for rendering unusual properties. In contrast to carbon nanotubes, boron nitride nanostructured materials, an IIIV compound with similar hexagonal structure to graphite, have more uniform electronic properties with a larger band gap (~5.8eV) than the CNTs. Besides, boron nitride nanotube (BNNT) is a unique tubular material combining ultimate strength, stable dielectric properties and transparency. Our research group has done research work on synthesizing novel nanostructured
materials in the C-B-N system such as diamond, cubic- and hexagonal-BN, boron nanowires and
nanotubes and 2D BN. Specifically, our research work on nanostructured diamond and BNNTs will be
presented and discussed.
