单壁碳纳米管(SWCNTs)被认为是分子电子学的关键部件。今天的单壁碳纳米管光刻技术缺乏在特定目标位置直接定向沉积的简单性、灵活性和速度。本文利用自来水笔纳米光刻技术(FPN)，在常温下对单壁碳纳米管进行了直接拉制和放置，并进行了化学鉴定和取向验证。通过这种排列的特定电触点的放置被演示和表征。具有取向的拉伸工艺的基本基础在其他相关系统中具有潜在的应用，例如无机纳米管、聚合物和生物分子。
Single-walled carbon nanotubes (SWCNTs) are considered pivotal components for molecular electronics. Techniques for SWCNT lithography today lack simplicity, flexibility, and speed of direct, oriented deposition at specific target locations. In this paper SWCNTs are directly drawn and placed with chemical identification and demonstrated orientation using fountain pen nanolithography (FPN) under ambient conditions. Placement across specific electrical contacts with such alignment is demonstrated and characterized. The fundamental basis of the drawing process with alignment has potential applications for other related systems such as inorganic nanotubes, polymers, and biological molecules.
