Details of how atomic structure responds to strain are essential for building a deeper picture of mechanics in nanomaterials. Here, we provide the first experimental evidence of atomic displacements associated with shear strain in single-walled carbon nanotubes (SWNTs) by direct imaging using aberration-corrected transmission electron microscopy. The atomic structure of a zig-zag SWNT is resolved with unprecedented accuracy and the strain induced by bending is mapped in two dimensions. We sho...Expand abstract
