摘要

Carbon nanotube complexes are known for their miraculous mechanical and electronic properties that are crucial for nano-electromechanical systems (MEMS). In this study, through molecular dynamics simulations we found for the first time that the electric field and temperature can be used to co-regulate a reversible change of cross-sectional configuration of single-wall carbon nanotubes (SWCNTs). We showed that the electric field can help induce the collapse of an SWCNT when it contains a water droplet, while the increase of temperature can quickly recover its configuration. This controllable bistability of SWCNTs is promising for the design of nanodevices such as electromechanical switches in NEMS.
