SGER: Atomic-Scale Electronic Properties of Carbon Nanotubes by Transmission Electron Energy Loss Spectroscopy

这是一个由材料科学家、理论物理学家和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。我们的目标是开发一个通用的电子能量损失（EELS）光谱技术，使用透射电子显微镜探测电子响应的单个碳纳米管在原子尺度上，并解释这种响应的基础上的理论模型的电子束-纳米管相互作用。该方法的优点是它是非接触的，并且可以允许对当前困难的和速率限制的将物理接触附接到碳纳米管以获得传输性质的方法的富有成效的替代。该项目为博士后助理提供了极好的教育机会。%这是一个由材料科学家、理论物理学家和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。该小组希望开发一种表征碳纳米结构电子传输特性的非接触方法。如果成功的话，该方法可以允许一个富有成效的替代目前困难和速率限制的方法，将物理接触连接到碳纳米管，以获得传输性能。这将有助于基于碳纳米结构的纳米电子学的功能设计。该项目为博士后助理提供了极好的教育机会。

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.
