Since the discovery of the superconductivity in boron-doped diamond [1], the carrier doping, especially boron doping in carbon materials attracts much attentions. For the carbon nanotube, however, the effect of boron doping as well as the possibility of the superconductivity [2] have not been well understood yet. Thus, we systematically study the boron-doped single-walled zigzag carbon nanotube...

Electrical sensitivity of a boron nitride nanotube (BNNT) was examined toward hydroquinone (C6H4(OH)2) molecule by using density functional theory (DFT) calculations at the B3LYP/6-31G(d) level, and it was found that the adsorption energy (Ead) of hydroquinone on the pristine nanotube is  a bout -7.77kcal/mol. But when nanotubes have been doped with Si and Al atomes, the adsorption energy of hy...

Nitrogen-doped carbon nanotubes (CNx)/carbon nanotube intramolecular junctions were prepared by a simple continuous chemical vapour deposition (CVD) method at 650 °C. The catalyst was obtained by calcination of a layered double hydroxide precursor containing Fe and Mg. By switching between hexane and ethylenediamine repeatedly in the CVD process, multiple intramolecular junctions composed of CN...

Electrical sensitivity of a beryllium oxide nanotube (BeONT) was examined toward aniline (C6H5 NH2) molecule by using Density Functional Theory (DFT) calculations at the B3LYP/6-31G (d) level, and it was found that the adsorption energy (Ead) of aniline on the pristine nanotubes is about -19.06kcal/mol. However, when nanotube has been doped by P a...

Abstract: Electrical sensitivity of a boron nitride nanotube (BNNT) was examined toward (C3H4) molecule by using density functional theory (DFT) calculations at the B3LYP/6-31G (d) level, and it was found that the adsorption energy (Ead) of methylacetylene (C3H4) the pristine nanotubes is a bout -1.78kcal/mol. But when nanotube have been doped with Si and Al atomes, the adsorption energy of me...
