The encapsulation of C 60 molecules inside double-walled carbon nanotubes (DWNTs) is realized by means of a plasma ion-irradiation method. Transmission electron microscopy observations confirm that DWNTs have been filled with C 60 fullerenes having amorphous morphology. More importantly, electrical transport measurements indicate that C 60 -encapsulated metallic DWNTs exhibit a novel negative differential resistance behavior.
