Electron Compton scattering and cathodoluminescence of 2D materials

电子康普顿散射是一种告诉我们原子如何聚集在一起形成固体材料的技术。为了使这项技术起作用，固体必须非常薄。在这个项目中，电子康普顿散射将应用于所谓的二维材料，它由单层原子组成。石墨烯就是一个例子，它是从石墨（铅笔所用的材料）中提取出来的。除了康普顿散射，我们还将使用另一种技术，阴极发光，来测量等离子体的行为（等离子体是固体中自由电子的振荡），这在光学领域是很重要的。

Electron compton scattering is a technique that tells us how atoms come together to form a solid material. For the technique to work the solid has to be extremely thin. In this project electron Compton scattering will be applied to so-called 2D materials, which consist of a single layer of atoms. An example is graphene, which is extracted from graphite (the material used in pencils). Apart from Compton scattering we will also use another technique, cathodoluminescence, to measure the plasmon behaviour (a plasmon is an oscillation of the free electrons in the solid), which is important in the field of optics.
