Formation of nanocrystals (or nanocrystals with core/shell structure) and applications for photonics, floating gate and magnetic memory. 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 ex ....Formation of nanocrystals (or nanocrystals with core/shell structure) and applications for photonics, floating gate and magnetic memory. 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
Switching mechanisms in nonvolatile resistive memory using high-k dielectrics. Growth in the use of portable electronic devices, such as cameras, phones and MP3 players has resulted in an increased demand for low-power, high-density, non-volatile memory (NVM). One class of such memories aims to use resistance changes in thin dielectric films as a means of storing information. This project aims to develop a better understanding of these devices and to develop new and innovative processes for co ....Switching mechanisms in nonvolatile resistive memory using high-k dielectrics.

Novel Fermion Actions for Lattice Gauge Theory. The Standard Model of the universe is founded on quantum field theories in which gauge bosons mediate the forces between fermions, the constituents of matter. For example, the gluon of Quantum Chromodynamics (QCD) mediates the strong interactions between quarks as they compose protons, and neutrons. The only way to reveal the long-distance properties of this fundamental gauge theory from first principles is to numerically simulate the theory on a s ....Novel Fermion Actions for Lattice Gauge Theory. The Standard Model of the universe is founded on quantum field theories in which gauge bosons mediate the forces between fermions, the constituents of matter. For example, the gluon of Quantum Chromodynamics (QCD) mediates the strong interactions between quarks as they compose protons, and neutrons. The only way to reveal the long-distance properties of this fundamental gauge theory from first principles is to numerically simulate the theory on a space-time lattice. Simulating fermions on a lattice has proved very challenging. This project will explore novel and innovative improved fermion algorithms for the general problem of gauge theories on the lattice.Read moreRead less
A programme to study quarkonium-like states at ATLAS. Particle physics, the study of the fundamental building blocks of matter, has pioneered the use of large collaborations --- hundreds of scientists working in dozens of countries --- to solve difficult research problems. Australian groups have contributed to several such experiments, studying cosmic rays, neutrinos, and broken symmetries, as well as developing ATLAS, a vast experiment dedicated to understanding the origin of mass.
