Rayleigh and Raman Scattering Spectroscopy of Individual Extreme Nanowires

极端纳米线可以说是最小的可能的周期性材料。通常，它们被定义为直径小于5 nm的线，并且它们表达的行为不容易与它们的较大对应物相比。填充碳纳米管允许在CNT内产生极端的纳米线，否则这些纳米线在化学和物理上是不稳定的。这种方法可以产生横截面小到单个原子的纳米线。该项目的目的是确定已知物理结构的单个极端纳米线的电子结构和振动模式。这将通过开发一个系统来实现，该系统用于对单个悬浮和填充的CNT进行瑞利和共振拉曼光谱，该系统还将通过高分辨率TEM成像。

Extreme nanowires are arguably the smallest possible periodic materials. Typically they are defined as wires with diameters of less than 5 nm, and they express behaviours not easily comparable to their larger counterparts. Filling carbon nanotubes allows the creation of extreme nanowires inside the CNTs that would otherwise be chemically and physically unstable. This method can produce nanowires with cross sections as small as single atom. The aim of this project is to determine the electronic structure and vibrational modes of individual extreme nanowires of known physical structure. This will be achieved by developing a system for performing Rayleigh and Resonance Raman spectroscopy on individual suspended and filled CNTs which will also be imaged by high resolution TEM.
