To form the individual heterostructure nanotube, we found that the CVD process could induce tensile strain in the suspended SWCNT, and resultantly the thermal conductivity of the SWCNT was enhanced by this uniaxial strain enabled by BNNT anchoring, which is the first experimental study to show the relation of the axial strain and the thermal conductivity of SWCNT. This implies that thermal-conductivity adjustable SWCNT materials could be fabricated making the best of this property. Besides, the efficiency of boron nitride coating on macroscopic SWCNT thin film has been evaluated by various optical spectroscopy, to provide important information about the heterostructure nanotubes. The electronic device applications of the heterostructure nanotubes are studies expensively, and the results will be published in the future. Therefore, the primary goals of the research plan are fulfilled as expected.
