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 s ....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.Read moreRead less

Summary
National Facility for Electron Spin Correlations and Spintronics. Conventional electronics is based on coupling the charge of the electrons with external electric fields and light. Recent work on spintronics is directed toward the use of both the spin (angular momentum) and the charge degrees of freedom of the electron. We currently lead the world in the development of spin-resolved coincidence measurements, which make it possible to determine previously inaccessible nanoscale magnetic propertie ....National Facility for Electron Spin Correlations and Spintronics. Conventional electronics is based on coupling the charge of the electrons with external electric fields and light. Recent work on spintronics is directed toward the use of both the spin (angular momentum) and the charge degrees of freedom of the electron. We currently lead the world in the development of spin-resolved coincidence measurements, which make it possible to determine previously inaccessible nanoscale magnetic properties, central to 'spintronic structure engineering'. State-of-the-art instrumentation is requested to characterise the magnetic and crystallographic structure, the adsorbates, and the lateral distribution and depth profile of fabricated zero, one and two-dimensional structures.Read moreRead less
Many-Electron Dynamics and Electronic Structure of Materials Studied by Electron Momentum Spectroscopy. Electron momentum spectroscopy is a technique that resembles playing pool with electrons. This technique, largely developed in Australia, determines the binding energy and velocity distribution of electrons in matter. This distribution, closely related to the quantum mechanical wave function of the electrons, can be compared directly with calculations of the electronic structure.

Electron momentum spectroscopy is a technique that resembles playing pool with electrons. This technique, largely developed in Australia, determines the binding energy and velocity distribution of electrons in matter. This distribution, closely related to the quantum mechanical wave function of the electrons, can be compared directly with calculations of the electronic structure. Such a comparison helps establish which theory approaches nature most closely, and thus improves our understanding of the electronic structure. This understanding helps to predict the properties of materials, and hence this knowledge will facilitate the design of materials with desirable properties.Read moreRead less
