Rayleigh and Raman Scattering Spectroscopy of Individual Extreme Nanowires

极端纳米线可以说是最小的周期性材料。通常，它们被定义为直径小于5纳米的导线，它们表现出的行为不容易与较大的导线相比较。填充碳纳米管可以在碳纳米管内部创建极端的纳米线，否则这些纳米线在化学和物理上都不稳定。这种方法可以制造出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个别极端纳米线的电子结构和振动模式。这将通过开发一种对单个悬浮和填充的碳纳米管进行瑞利和共振拉曼光谱的系统来实现，该系统也将由高分辨率的电子显微镜成像。

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.
