Locked twist in multiwalled carbon-nanotube ribbons

Abstract

Twisted multiwalled carbon-nanotube (MWCNT) ribbons were observed with transmission electron microscopy. Particularly one cantilevered MWCNT ribbon had a twist present in the freestanding segment. An energetics analysis was presented supporting the hypothesis that twists in MWCNT ribbons are stabilized through more favorable atomic registry between neighboring layers in the twisted state.
