Atomic resolution STM imaging of a twisted single-wall carbon nanotube
arXiv:cond-mat/9804175 · doi:10.1103/PhysRevB.58.R4266
Abstract
We present atomically-resolved STM images of single-wall carbon nanotubes (SWNTs) embedded in a crystalline nanotube rope. Although they may be interpreted as of a chiral nanotube, the images are more consistently explained a an achiral armchair tube with a quenched twist distortion. The existence of quenched twists in SWNTs in ropes might explain the fact that both as-grown bulk nanotube material and individual ropes have insulator-like conductivity at low temperature.
