Tubular structures of GaS [PDF]

open access: yes, 2004
In this Brief Report we demonstrate, using density-functional tight-binding theory, that gallium sulfide (GaS) tubular nanostructures are stable and energetically viable.

Towards Exciton-Polaritons in an Individual MoS2 Nanotube

open access: yesNanomaterials, 2020
We measure low-temperature micro-photoluminescence spectra along a MoS 2 nanotube, which exhibit the peaks of the optical whispering gallery modes below the exciton resonance.

Structural selective charge transfer in iodine-doped carbon nanotubes [PDF]

open access: yes, 2006
We have investigated iodine intercalated carbon nanostructures by extended X-ray absorption fine structure (EXAFS) and Raman spectroscopies. We discuss here the charge transfer and the iodine–carbon interaction as a function of the carbon nanostructures (

Field-effect transistors assembled from functionalized carbon nanotubes

open access: yes, 2006
We have fabricated field effect transistors from carbon nanotubes using a novel selective placement scheme. We use carbon nanotubes that are covalently bound to molecules containing hydroxamic acid functionality.

Elastomeric carbon nanotube circuits for local strain sensing [PDF]

open access: yes, 2006
We use elastomeric polydimethylsiloxane substrates to strain single-walled carbon nanotubes and modulate their electronic properties, with the aim of developing flexible materials that can sense local strain.

Hydrogen Sensing with Ni-Doped TiO2 Nanotubes

open access: yesSensors, 2013
Doping with other elements is one of the efficient ways to modify the physical and chemical properties of TiO2 nanomaterials. In the present work, Ni-doped TiO2 nanotubes were fabricated through anodic oxidation of NiTi alloy and further annealing ...

Dielectric Meta-lattices with Tunable Reflectivity

open access: yesJournal of Mathematical and Fundamental Sciences, 2022
We report a study on the reflective performance of a dielectric meta-lattice formed by a one-dimensional periodic arrangement of silicon nanotubes. It was found that switching from transparent state to reflective state can be done by simply varying one ...

Exciton diffusion in air-suspended single-walled carbon nanotubes [PDF]

open access: yes, 2010
Direct measurements of the diffusion length of excitons in air-suspended single-walled carbon nanotubes are reported. Photoluminescence microscopy is used to identify individual nanotubes and to determine their lengths and chiral indices.

Carbon nanotube biosensors [PDF]

open access: yesFrontiers in Chemistry, 2015
Nanomaterials possess unique features which make them particularly attractive for biosensing applications. In particular, carbon nanotubes (CNTs) can serve as scaffolds for immobilization of biomolecules at their surface, and combine several exceptional physical, chemical, electrical, and optical characteristics properties which make them one of the ...
