Multiwalled carbon nanotube bridges and junctions using nanomanipulators.
We have characterized electromechanical properties of multiwalled carbon nanotubes (MWCNTs) by using three-dimensional nanomanipulators that were installed inside the field-emission scanning electron microscope (FESEM). A single carbon nanotube was bridged between two nanopositioners, where the bending angle was easily controlled by two nanopositioners. Contrary to the previous report, we observed that conductance varied several times with the bending. The conductance increased at a larger bending angle. The discrepancies from single-walled carbon nanotubes were further discussed.
