The structural changes in an isolated carbon nanotube during superplastic elongation are studied using a in situ transmission electron microscopy equipped with a nanomanipulation system. Nanobeam electron diffraction reveals the chiral indices of the nanotube decrease by (1, 1) when tensile stress and electroresistive heating are simultaneously applied. The change in the chiral indices corresponds to the migration of just two pairs of defects in the nanotube walls. The experiment allows the dynamics of plastic deformation to be understood at the atomistic level, which will be beneficial for constructing advanced devices with utilization of nanotubes.
