Methyl Acetylene Detection by BN Nanotube: DFT Studies [PDF]

International Journal of New Chemistry, 2014
: 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)

Subband population in a single-wall carbon nanotube diode

, 1999
We observe current rectification in a molecular diode consisting of a semiconducting single-wall carbon nanotube and an impurity. One half of the nanotube has no impurity, and it has a current-voltage (I-V) charcteristic of a typical semiconducting ...

Continuum modeling for lithium storage inside nanotubes

Frontiers in Physics, 2023
Lithium storage and capture are of particular importance for the development of new technology in electric vehicles and portable electronics. Nanotubes (NTs) are among many porous nanomaterials offered as potential candidates for lithium storage. In this

Surface patterning of carbon nanotubes can enhance their penetration through a phospholipid bilayer

, 2012
Nanotube patterning may occur naturally upon the spontaneous self-assembly of biomolecules onto the surface of single-walled carbon nanotubes (SWNTs). It results in periodically alternating bands of surface properties, ranging from relatively hydrophilic

Nanospintronics with carbon nanotubes [PDF]

, 2006
One of the actual challenges of spintronics is the realization of a spin-transistor allowing to control spin transport through an electrostatic gate. In this review, we report on different experiments which demonstrate a gate control of spin transport in

Computing Fourth Atom-bond Connectivity Index of V-Phenylenic Nanotubes and Nanotori

Acta Chimica Slovenica, 2013
Among topological descriptors connectivity topological indices are very important and they have a prominent role in chemistry. One of them is atom-bond connectivity (ABC) index defined as ABC(G)= [formula:see text], in which degree of vertex v denoted ...

Electrical and Structural Analysis of CNT-Metal Contacts in Via Interconnects [PDF]

, 2015
Vertically aligned carbon nanotubes grown by plasmaenhanced chemical vapor deposition offer a potentially suitable material for via interconnects in next-generation integrated circuits. Key performance-limiting factors include high contact resistance and

Atomic resolution STM imaging of a twisted single-wall carbon nanotube

, 1998
We present atomically-resolved STM images of single-wall carbon nanotubes (SWNTs) embedded in a crystalline nanotube rope. Although they may be interpreted as of a chiral nanotube, the images are more consistently explained a an achiral armchair tube ...

Variable and reversible quantum structures on a single carbon nanotube [PDF]

, 2000
The band gap of a semiconducting single wall carbon nanotube decreases and eventually vanishes leading to metalization as a result of increasing radial deformation.
