Chirality-Dependent Motion Transmission between Aligned Carbon Nanotubes

Abstract

I demonstrate a directional motion-transmission behavior of aligned carbon nanotubes (CNTs) using atomistic simulations. The network of overlapping $\pi$ orbitals at the interface act as gear teeth to translate the sliding motion of a CNT into a rotating motion of the adjacent CNT, or \textit{viceversa}. The efficiency of this orthogonal motion transmission is found to strongly depend on the tube chirality, by which the interfacial stacking configuration of the atoms is determined. These results have strong implications on the design of the motion transmission system at the nanoscale.
