Abstract

The strain-induced change in a carbon-nanotube diffraction pattern is found after applying strain, using a microelectromechanical tensile stage, to the outer shell of a double-walled carbon nanotube, while the inner shell provides an unstrained reference pattern. The nanotube is found to have chirality (63,21)@(65,32) with 16-20° tilt and strain up to 1% in the outer shell.

Keywords: carbon nanotubes; chirality; electron diffraction; strain.
