ASSEMBLED SORTER SINGLE-WALLED CARBON NANOTUBES STAND-ON GOLD FILM SURFACE
竖立在晶态金表面上的短单壁碳纳米管

The single-walled carbon nanotubes(SWCNTs) are synthesized and purified. A water colloid of SWCNTs is prepared and used to assemble SWCNTs on a gold film surface. Its STM image shows sorter SWCNTs standing-on gold film surface. The crystal grain image of gold thin film and an atomic structure of highly oriented pyrolytic graphite (HOPG) are observed using a scanning tunneling microscope (STM) with the SWCNT tip made from the water colloid mentioned above. The SWCNTs standing-on gold film surface is very important for measuring electronic properties of carbon nanotubes, fabricating field emission cathode, structuring nanoelectronic devices, and making tips of a scanning probe microscope (SPM).
