http://www.sciencedirect.com/science/journal/aip/09270256The melting and soldering processes of two iron filled carbon nanotubes is explored by means of classicalmolecular dynamics, in order to develop an understanding of the underlying mechanisms that govern thedynamics of nano-soldering. Molten Fe flows from the open end of the two CNTs, leading to a liquid junc-tion, and eventually to a solid contact. This soldering process is accompanied by partial or total healing ofthe carbon nanotubes, which after cooling and relaxation form just a single unit which encapsulates theiron, depending on the relative separation, diameters and axial offset of the nanotubes. This makes for apromising scenario for CNT soldering, repairing and healing, and a variety of different tools in the field ofnanoelectronics.
