Abstract 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 highly oriented pyrolytic graphite (HOPG) are observed using a scanning tunneling microscope(STE) with the SWCNT tip made from the water colloid mentioned above.The SWCNTs standing-on gold film surface is very important for measuring electronic properteis of carbon anotubes,fabricating field emission cathode,structing nanoelectrnic devices,and makign tips of a scannign probe microscope(SPM).
