| Abstract: | Carbon nanotubes have attracted much attention as new probe tips for Atomic Force Microscopy due to their tiny diameter and excellent mechanical properties. In this paper, a new method was developed to assemble a carbon nanotube onto a tungsten tip. This tip was then used as probe of Scanning Tunneling Microscopy and got clear step image of high ordered pyrolytic graphite (HOPG) surface. |

| Keywords: | carbon nanotube tungsten tip scanning tunneling microscopy |
