Summary
A prototype Scanning Helium Atom Microscope (SHeM) for soft materials. The scanning helium atom microscope (SHeM) has been a tantalising prospect since the birth of quantum physics. The SHeM would have unparalleled resolution and would be completely non-damaging; potentially revolutionising the imaging of soft delicate materials. This project will develop the first SHeM instrument in Australia to study soft matter.
Phonon based condensed matter imaging. This project will exploit observations of phonon-based chemical contrast in the SHeM to determine the physics that underpins the imaging mechanism and use them to probe vibrational processes in condensed matter imaging. Imaging is an essential tool for the discovery, application and fabrication of new materials, structures and devices. However, many delicate structures are irrevocably degraded and changed when imaged using conventional microscopy. This team ....Phonon based condensed matter imaging. This project will exploit observations of phonon-based chemical contrast in the SHeM to determine the physics that underpins the imaging mechanism and use them to probe vibrational processes in condensed matter imaging. Imaging is an essential tool for the discovery, application and fabrication of new materials, structures and devices. However, many delicate structures are irrevocably degraded and changed when imaged using conventional microscopy. This team recently invented the scanning helium atom microscope (SHeM), which can image surfaces non-destructively with nanoscale resolution. They will use the SHeM to determine the new fundamental physics that underpins the imaging mechanism. Outcomes include turning SHeM into a tool that materials and biological scientists can use in laboratories worldwide.Read moreRead less
Hot Topic: Quantum Design of Phononic Heat Filters. Heat management is critical to many technologies for sustainable energy, electronics, protective equipment and energy-efficient buildings.

Heat management is critical to many technologies for sustainable energy, electronics, protective equipment and energy-efficient buildings. The phonon is the quantum particle representing a travelling vibration and is responsible for the transmission of heat in solids. This project will study the new mechanisms for phonon transport in solids modified with embedded nanoparticles, which operate as phononic filters. Neutron spectroscopy provides a tool to measure the phonon density of states which is critical for developing a mathematical model of thermal boundary resistance. This is expected to identify mechanisms for ultra-low thermal conductivity leading to potential applications in thermoelectric generators and heat-resistant materials.Read moreRead less
Enabling semiconductor nanowire technologies via 3D atomic-scale insight. Semiconductor nanowires (NWs) are nanotechnology building blocks that have the potential to transform solar cells, light emitting diodes, lasers and transistors, creating new industries in communications, energy and healthcare. The industrial development of NWs has been blocked by uncertainties in the relationships between their growth conditions, properties and atomic-scale structure.

Semiconductor nanowires (NWs) are nanotechnology building blocks that have the potential to transform solar cells, light emitting diodes, lasers and transistors, creating new industries in communications, energy and healthcare. The industrial development of NWs has been blocked by uncertainties in the relationships between their growth conditions, properties and atomic-scale structure. This project will address this challenge by establishing a rigorous framework for these relationships. The project aims to achieve this by harnessing the unique power of atom probe microscopy to reveal the NW structure in three dimensions, and at atomic-resolution. The project aims to place Australian research at the frontier of development of these future industries.Read moreRead less

Ultrafast time resolved optical spectroscopy for advanced multifunctional materials: Time resolved spectroscopy is among the hottest emerging fields in condensed matter physics and offers a new perspective into the complex physics of multifunctional materials like multiferroics or unconventional superconductors. At present, the underlying physics of these novel complex materials is not fully understood and new experimental approaches such as the proposed time-resolved optical spectroscopy are required. The deeper understanding of the involved phenomena would also allow for a systematic search for new, undiscovered multifunctional materials with similar but enhanced properties. This offers a huge potential for future industry in applications such as in novel sensors, information processing, and high efficiency photovoltaics.Read moreRead less

Recent advances in growth methods such as pulsed laser deposition enable layer-by-layer growth with atomic precision. The aim of this project is to combine complementary experimental methods (ie neutron scattering and optical spectroscopy), in order to gain a detailed insight into the magnetic and electronic properties of the heterostructures. This is designed to yield a deeper understanding of the underlying physics in order to help develop new materials for next-generation information technology.Read moreRead less

The recent discovery of topological insulators reveals the tip of the iceberg, but many theoretical hypotheses, such as the existence of the fractional Chern insulator and quantum spin liquid, remain elusive. This project aims to bridge the gap between conceptual models and real materials by using first-principles calculations. The plan is to identify and engineer topological electronic bands in experimentally feasible materials, characterise existing quantum frustrated materials and connect these materials with minimal theoretical models. This project also aims to reveal further families of topological materials and clarify their physical properties.Read moreRead less
