Abstract

The electrical probing and engineering of copper-filled amorphous-like carbon nanotubes (CNTs) inside a 300 kV high-resolution TEM was studied. The copper-filled nanotubes were synthesized by pyrolysis of copper(II)- acetylacetonate at low-pressure conditions. The existence of tiny metal particles inside the tubes was also documented. The whole process was carried out inside a JEM-3100FEF field-emission high-resolution transmission electron microscope using a Nanofactory Instruments piezo-driven STM-TEM stage. High-precision nanowelding of contacting Cu-filled nanotubes was achieved inside the TEM. The Cu mass flow rate was estimated to be as fast as ca. 0.5 fgs ^-1 according to real-time TEM video recording.
