Abstract

Low-temperature scanning tunneling microscopy measurements were performed on single-wall carbon nanotubes that are freely suspended over a trench. On a Pt substrate with predefined trenches etched into it, the nanotubes were grown by chemical vapor deposition. Spatially resolved spectroscopy on the suspended portion of both metallic and semiconducting nanotubes was achieved. The results show that the spacing of the Coulomb blockade peaks changed with tip position reflecting a changing tip-tube capacitance.
