Phys. Rev. B 67, 033407 (2003) [4 pages]Plastic deformations in mechanically strained single-walled carbon nanotubesReceived 9 October 2002; published 22 January 2003 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 intra-tube electronic scattering above a threshold strain of ∼5–10 %. These findings are consistent with theoretical calculations predicting the onset of plastic deformation and defect formation in carbon nanotubes. © 2003 The American Physical Society URL:
