Packing C ₆₀ in Boron Nitride Nanotubes

Abstract

We have created insulated C60 nanowire by packing C60 molecules into the interior of insulating boron nitride nanotubes (BNNTs). For small-diameter BNNTs, the wire consists of a linear chain of C60 molecules.With increasing BNNT inner diameter, unusual C60 stacking configurations are obtained (including helical, hollow core, and incommensurate) that are unknown for bulk or thin-film forms of C60.C60 in BNNTs thus presents a model system for studying the properties of dimensionally constrained "silo" crystal structures. For the linear-chain case, we have fused the C60 molecules to form a single-walled carbon nanotube inside the insulating BNNT.

Van der Waals Interaction between Two Crossed Carbon Nanotubes

“…The VDW forces are very critical for understanding the growth mechanism of fullerenes and nanotubes 13,14,15 and formation process of ropes and bundles 16,17,18 . Potentials for graphite layers 19,20 , two fullerenes 21,22,23,24 , fullerene and surface 25,26 , nanotube and surface 9,27,28 , fullerenes inside and outside of nanotubes 29,30,31,32,33 are well studied. There are a number of publications devoted to interaction between the inner and the outer parallel tubes such as single-(SWNTs) 29,34,35,36 , double- 37,38 , and multi-wall nanotubes (MWNTs) 39,40,41 .…”

Growth of Boron Nitride Nanohorn Structures

“…2,3) Boron nitride (BN) nanostructured materials with a bandgap energy of $6 eV and non-magnetism are also expected to show various electronic, optical and magnetic properties such as Coulomb blockade, photoluminescence, and supermagnetism. 4,5) Recently, several studies have been reported on BN nanomaterials such as BN nanotubes, [6][7][8] BN clusters, 9,10) BN nanocapsules 4,5,11) and BN nanoparticles, 12,13) which are expected to be useful as electronic devices, high heatresistance semiconductors and insulator lubricants. In addition, some BN nanohorns as a novel type of BN nanotubes were also reported by HREM images.…”
