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.

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

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

Ultrafast laser deposition - a process pioneered by the Applicants - has already demonstrated record yields in the production of carbon-based nano-clustered materials with better control over the size of the nano-particles than any other process. This project aims to improve fundamental understanding of the ultra-fast laser deposition method of nano-fabrication through theoretical and experimental studies, which accurately correlate the ablation conditions to the structural, electronic, magnetic and optical properties of resulting nano-particles. The results will be applied to efficiently produce nano-clustered materials with tuneable properties for a wide range of new technologies such as spintronics, biophotonics, and nanoclinics.Read moreRead less

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

Materials that contain nanometre-sized crystallites of a second material can exhibit novel optical, electrical and magnetic properties that have direct technological application. However, it is often difficult to control the size and concentration of the small crystals using conventional synthesis techniques. This project will overcome these limitations by exploiting the unique properties of pulsed-laser heating to produce the crystals. It will also investigate the optical, electrical and magnetic properties of these new materials and asses their suitability for super-dense data storage, solid-state lighting and advanced detection systems.Read moreRead less
