Abstract

The presence of ad-dimers on carbon nanotubes under tension leads to the formation of defects that wrap themselves around the circumference of the nanotube. These defects are actually short segments of a tube with a changed helicity, which suggests that the combination of ad-dimers plus strain can be used to form nanotube-based quantum dots. Our classical molecular dynamics and tight binding simulations show that the formation of such structures is particularly clean and promising for the n,0 zigzag tubes, where the presence of ad-dimers induces plastic transformations on what are otherwise brittle tubes.
