The effect of mechanical deformation on the electrical characteristics of individual multiwall carbon nanotubes (MWCNTs) was investigated by a nanoprobe manipulation technique in a transmission electron microscope (TEM). The electrical conductivity was measured during the deformation of the MWCNT in TEM. The electrical conductivity of the MWCNTs was sensitive to structural variation. The electromechanical characteristics were reversible within the elastic limit. However, when lattice defects were formed due to deformation, the electrical conductivity was not restored to the original state, even when the applied stress was released.
