Theoretical study of thermal conductivity in single-walled boron nitride nanotubes

Thermal conductivity of single-walled carbon nanotubes

We have measured the temperature-dependent thermal conductivity k(T) of crystalline ropes of singlewalled carbon nanotubes from 350 K to 8 K. k(T) decreases smoothly with decreasing temperature, and displays linear temperature dependence below 30 K. Comparison with electrical conductivity experiments indicates that the room-temperature thermal conductivity of a single nanotube may be comparable...

Heteroepitaxial Growth of Single-Walled Carbon Nanotubes from Boron Nitride

The growth of single-walled carbon nanotubes (SWCNTs) with predefined structure is of great importance for both fundamental research and their practical applications. Traditionally, SWCNTs are grown from a metal catalyst with a vapor-liquid-solid mechanism, where the catalyst is in liquid state with fluctuating structures, and it is intrinsically unfavorable for the structure control of SWCNTs....

Vibroelectronic Properties of Functionalized Single- Walled Carbon Nanotubes and Double-walled Boron Nitride Nanotubes

Theoretical study on interaction of hydrogen with single-walled boron nitride nanotubes. II. Collision, storage, and adsorption.

Collision and adsorption of hydrogen with high incident kinetic energies on a single-walled boron nitride (BN) nanotube have been investigated. Molecular-dynamics (MD) simulations indicate that at incident energies below 14 eV hydrogen bounces off the BN nanotube wall. On the other hand, at incident energies between 14 and 22 eV each hydrogen molecule is dissociated at the exterior wall to form...
