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.

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。为了使这项技术发挥作用，固体必须非常薄。在这个项目中，电子康普顿散射将被应用于所谓的2D材料，其中包括一个单一的原子层。一个例子是石墨烯，它是从石墨（铅笔中使用的材料）中提取的。除了康普顿散射，我们还将使用另一种技术，阴极发光，来测量等离子体激元行为（等离子体激元是固体中自由电子的振荡），这在光学领域很重要。
