Recent studies at the Rensselaer Polytechnic Institute have shown that electric field can have a profound effect on individual carbon nanotube ensembles. We have shown that nanotubes can be aligned along the electric field lines, and can also be made to move along the field lines above a critical or threshold electric field. Experiments were repeated with nano-particles such as C-60 (fullerenes) and these effects were not observed, which indicates that the aspect ratio and one-dimensionality of the nanotubes plays a critical role. These observations can foreshadow novel electro-mechanical applications for nanotube elements.
