Electron Momentum Spectroscopy of Correlated Nanoscale Structures

电子关联在决定凝聚态物质和纳米结构的电子性质方面起着至关重要的作用。 材料最基本的电子性质是它的光谱动量密度，这主要取决于电子相关性。 它可以通过电子动量谱唯一地测量，甚至对于无定形和无序的材料。 我们将使用我们新的世界领先的电子动量谱仪来测量相关系统的纳米厚样品的电子结构，如合金，超导体和降维结构。 这些测量结果将用于测试为描述这些纳米结构的行为而开发的理论。

Electron correlations play a vital role in determining the electronic properties of condensed matter and nanoscale structures. The most fundamental electronic property of a material is its spectral momentum density and this depends critically on electron correlations. It can be measured uniquely by electron momentum spectroscopy, even for amorphous and disordered materials. We will use our new world-leading electron momentum spectrometer to measure the electronic structure of nanometer thick samples of correlated systems, such as alloys, superconductors, and reduced dimensional structures. These measurements will be used to test theories developed to describe the behaviour of these nanoscale structures.
