Electron Momentum Spectroscopy of Correlated Nanoscale Structures. 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.
