摘要：

Single-wall carbon nanotubes (SWCNTs) have been synthesized and purified. Using a water colloid, SWCNTs have been assembled at the end of a tungsten tip that can be used as the scanning tunneling microscope (STM) tip, and atomic resolution images of highly oriented pyrolytic graphite (HOPG) and gold film surfaces have been obtained. The field emission properties of SWCNTs have also been studied exploiting the field emission microscopy (FEM). A field emission pattern of an SWCNT at atomic resolution was observed, which was consistent with the calculated results of the (9,9) armchair SWCNT. Electron transport properties along SWCNTs were investigated, negative differential conductance was observed. (C) 2001 Elsevier Science B.V. All rights reserved.
