article description
Molecular junctions formed by a single carbon chain (SCC) bridging two SWCNTs are highly desirable for molecular electronic nanodevices; however, the fabrication is still quite challenging. In this study, we present a novel method to produce a SCC bridging the outer wall of two SWNTs. By separating the carbon nanotube embedding nanobuds junction, carbon atom chain including a few tens of atoms or even up to 100 carbon atoms bridging two SWNTs can be formed. Moreover, we find that embedding nanobuds junction shows extraordinary room temperature superplasticity. The laddering effect, in which the atom chain can be continuously pulled out from the fullerene molecule in the nanobuds junction under tensile loading, is exhibited in this work.
