Electronic properties of mechanically induced kinks in single-walled carbon nanotubes
نویسندگان
چکیده
We have used an atomic-force microscope tip to mechanically buckle single-walled carbon nanotubes. The resistance of the induced defects ranged from 10 to 100 kV and varied with the local Fermi level, as determined by scanned-gate microscopy. By forming two closely spaced defects on metallic nanotubes, we defined quantum dots less than 100 nm in length. These devices exhibited single-electron charging behavior at temperatures up to ;165 K. © 2001 American Institute of Physics. @DOI: 10.1063/1.1377316#

Plastic deformations in mechanically strained single-walled carbon nanotubes
Antiferromagnetic manipulation was used to controllably stretch individual metallic single-walled carbon nanotubes ~SWNT’s!. We have found that SWNT’s can sustain elongations as great as 30% without breaking. Scanned gate microscopy and transport measurements were used to probe the effects of the mechanical strain on the SWNT electronic properties, which revealed a strain-induced increase in in...

Determination of the mechanical properties of carbon nanotubes is an essential step in their applications from macroscopic composites to nano-electro-mechanical systems. In this paper we report the results of a series of molecular dynamics simulations carried out to predict the elastic constants, i.e. the elements of the stiffness tensor, and the elastic moduli, namely the Young’s and shear mod...
