Radial deformation measurements of isolated pairs of single-walled carbon nanotubes

Interactions between atoms of bound single-walled carbon nanotubes (SWNTs) are known to cause measurable distortion to the tube’s original circular cross-section frame. High-resolution transmission electron microscope (TEM) investigation was used here to directly image and verify these radial deformations. The data presented here provide, for the first time, direct measurements of the deformations due to the interactions between isolated pairs of nanotubes. The deformation data is compared to previously reported experimental and simulation results.
