一个单独的多壁碳纳米管（MWNT）和它的接触，焊接到共面波导（CPW）的电响应，测量高达24 GHz的使用技术，消除环境的影响。这是第一次从CPW中系统地分离出MWNT接触效应。每一种接触反应都有很大的不同，并且对环境光也表现出明显的敏感性。添加更多的接触材料明显改变了高频电响应和对光的敏感性。
The electrical response of an individual multiwalled carbon nanotube (MWNT) and its contacts, welded to a coplanar waveguide (CPW), was measured up to 24 GHz using a technique that removes environment effects. This is the first time MWNT contact effects have been systematically isolated from the CPW. Each contact response was quite different and also showed a pronounced sensitivity to ambient light. Adding more contact material clearly changed the high-frequency electrical response and the sensitivity to light.
