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

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一个探索性研究小赠款(SGER)项目。其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。这种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案，以取代目前困难和限速的方法，即将物理接触连接到碳纳米管以获得传输特性。该项目为博士后提供了一个很好的教育机会。%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为探索性研究(SGER)提供的小额资助项目。该小组希望开发一种非接触的方法来表征碳纳米结构的电子传输特性。如果成功，该方法可以提供一个富有成效的替代方案，取代目前困难和限速的方法，即将物理接触连接到碳纳米管上，以获得传输特性。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一个极好的教育机会。

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.
