Abstract

Abstract : An in situ transmission electron microscopy study of few‐chain NbSe3 encapsulated within the hollow core of carbon nanotubes is presented, where the tube/chain system is subjected to applied axial electrical currents. Electromigration and thermal excitation forces result in collective and individual chain dynamics, with concomitant radial deformations of the encapsulating tubes. Abstract : Axial electrical currents applied to multiwall carbon nanotubes filled with chains of the transition metal trichalcogenide NbSe3 drive the chains to collective or independent chain motions, as revealed by in situ transmission electron microscopy.
