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.

Key words: carbon nanotube, tungsten tip, scanning tunneling microscopy

摘要: 探索了用高频交变电场电泳辅助钨针尖粘碳管来组装CNT针尖的有效方法,比较得出实验的最佳参数。用该方法制作的CNT针尖用于扫描隧道显微镜(STM),得到了高定向石墨表面的阶梯像。
