Crosstalk between nanotube devices: contact and channel effects
, 2006 At reduced dimensionality, Coulomb interactions play a crucial role in determining device properties. While such interactions within the same carbon nanotube have been shown to have unexpected properties, device integration and multi-nanotube devices ...

Locally addressable tunnel barriers within a carbon nanotube [PDF]
, 2003 We report the realization and characterization of independently controllable tunnel barriers within a carbon nanotube. The nanotubes are mechanically bent or kinked using an atomic force microscope, and top gates are subsequently placed near each kink ...

A DFT Study on the Interaction of Doped Carbon Nanotubes with H2S, SO2 and Thiophene
Quantum Reports, 2021 The interactions of simple and Al-, B-, N-, S-, P-, and Si-doped carbon nanotubes with three sulfur-containing molecules (H2S, SO2, and thiophene) were investigated to assess their adsorption potencies and sensor abilities.

Hydroquinone Detection by BN Nanotube: DFT Studies [PDF]
International Journal of New Chemistry, 2014 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 ...

Elastic Properties of Carbon nanotubes : An atomistic approach
, 2007 Energetically the single sheet of graphite (graphene) is more stable than the nanotube. The energy difference between the two systems can be directly related to the strain energy involved in rolling up the graphene sheet to form the nanotube.

Torsional Dynamic Response of a Carbon Nanotube Embedded in Visco-Pasternak’s Medium
Mathematical Modelling and Analysis, 2016 The torsional dynamics of carbon nanotubes embedded in viscoelastic medium are presented by using the nonlocal elasticity theory. The medium is considered as a foundation model which characterized by the linear Winkler’s modulus, Pasternak’s (shear ...
