Kinematics of electromigration-driven sliding of Co nanorod fillers inside multi-walled carbon nanotubes.

ABSTRACT: The movement of Co nanorods driven by electromigration inside multi-walled carbon nanotubes was observed using in situ transmission electron microscopy. This study provides a unique method of experimental determination of both the electromigration force strength and sliding friction. When the tip of a biased electrode was located within the portion of a Co nanorod filler and an electric current was applied to push a part of the Co filler along the flow of electrons, the Co filler showed a trigonometric motion. Both the electromigration force strength and sliding friction were determined by analysis of the trigonometric movements. When a reversed electric current was applied to pull a part of the Co nanorod filler, its motion was hyperbolic-cosine like, and the motion was not suitabl
