This a Small Grants for Exploratory Research (SGER) project from an interdisciplinary group composed of a materials scientist, a theoretical physicist and a synthetic chemist. The objective is to develop a versatile electron energy loss (EELS) spectroscopy technique using a transmission electron microscope to probe electronic response of a single carbon nanotube at the atomic scale and to explain this response based on a theoretical model of electron beam - nanotube interaction. The virtue of the approach is that it is non-contact, and may allow a fruitful alternative to the currently difficult and rate-limiting approach of attaching physical contacts to the carbon nanotubes in order to obtain transport properties. The project offers an excellent educational opportunity for a post-doctoral associate.%%%This a Small Grants for Exploratory Research (SGER) project from an interdisciplinary group composed of a materials scientist, a theoretical physicist and a synthetic chemist.

If successful, the method could allow a fruitful alternative to the currently difficult and rate-limiting approach of attaching physical contacts to the carbon nanotubes in order to obtain transport properties. This would facilitate the functional design of nanoelectronics based on carbon nanostructures. The project offers an excellent educational opportunity for a post-doctoral associate.***

这是一个由一名材料科学家、一名理论物理学家和一名合成化学家组成的跨学科小组的探索性研究（SGER）小额赠款项目。目的是开发一种通用的电子能量损失（EELS）光谱技术，利用透射电子显微镜在原子尺度上探测单个碳纳米管的电子响应，并基于电子束-纳米管相互作用的理论模型来解释这种响应。该方法的优点是它是非接触的，并且可以提供一种富有成效的替代方法，以取代目前困难和限速的方法，即在碳纳米管上附加物理接触以获得输运性质。该项目为博士后提供了良好的教育机会。这是一个探索性研究（SGER）小额资助项目，由一个跨学科小组组成，该小组由一名材料科学家、一名理论物理学家和一名合成化学家组成。该小组希望开发一种非接触方法来表征碳纳米结构的电子输运特性。如果成功的话，该方法可以提供一种富有成效的替代方法，以取代目前困难且速率限制的方法，即在碳纳米管上附加物理接触以获得输运特性。这将促进基于碳纳米结构的纳米电子学功能设计。该项目为博士后提供了良好的教育机会
