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
Foundation studies of ion-beam nanotechnology. The impact of a single fast atom with sensitive materials leaves a path of latent damage with a diameter of around 10 nm. This latent damage can be developed to create nanostructures in a novel technique called ion beam nanomachining. We propose to create a method for using single atom impacts to produce nanomachined structures with novel physical and optical properties. This will be done by use of an active substrate that functions as a detector s ....Foundation studies of ion-beam nanotechnology.

Unlocking the potential of quantitative x-ray micro-tomography. This project aims to build on two new ideas in data acquisition and 3D image reconstruction to bring 3D X-ray microscopy or computed tomography (CT) into advanced research use as well as common industrial applications. In the past 10 years, CT has improved our understanding in areas ranging from the evolution of life and osteoporosis to composite material failure and oil recovery. However, the full potential of CT remains unrealised ....Unlocking the potential of quantitative x-ray micro-tomography. This project aims to build on two new ideas in data acquisition and 3D image reconstruction to bring 3D X-ray microscopy or computed tomography (CT) into advanced research use as well as common industrial applications. In the past 10 years, CT has improved our understanding in areas ranging from the evolution of life and osteoporosis to composite material failure and oil recovery. However, the full potential of CT remains unrealised because crucial features in structure and composition are overlooked by simplistic algorithms. Users cannot directly capture quantities of interest such as key compositional variation or defects, and workflows are poorly adapted for large-scale use in industrial fabrication or phenomics. This project aims to address these shortcomings using advanced mathematics and algorithms.Read moreRead less

This project aims to study the fundamental processes governing interaction of ultrafast light pulses with an important class of ferroelectric materials. In particular, it will investigate the physics of light-induced ferroelectric domain reversal in various types of ferroelectrics. Project outcomes will lead to the development of a novel, ultrafast laser domain patterning technique for application in nonlinear photonics, optical memories, and photovoltaics. This technique will be employed to create the first example of three-dimensional domain patterns for versatile wave interactions. This project expects to expand Australia's knowledge in ultrafast laser engineering of materials and contribute towards its rapid uptake by industries, with great potential for commercialisation.Read moreRead less
Dopant engineering of diamond for quantum sensing technologies. Doped diamonds are central to a growing range of quantum-sensing technologies for future industries, including medical and defence. These diamonds must be doped with both an electron donors and active 'quantum-defects' to operate. Within existing devices, the electronic donors also create parasitic magnetic noise, due to their magnetic-spin properties. In this project we aim to investigate the growth of diamond with new electronic d ....Dopant engineering of diamond for quantum sensing technologies. Doped diamonds are central to a growing range of quantum-sensing technologies for future industries, including medical and defence. These diamonds must be doped with both an electron donors and active 'quantum-defects' to operate. Within existing devices, the electronic donors also create parasitic magnetic noise, due to their magnetic-spin properties. In this project we aim to investigate the growth of diamond with new electronic donors, aiming for spin-free and thus noise-free dopant properties. This should provide significant benefits to defence capability, through enhanced magnetic anomaly detection in naval environments, and health outcomes, through neural sensing of brain signals at room temperature.Read moreRead less

We have discovered a method to make silicon highly enriched in the desirable spin-zero isotope using readily available ion implantation tools. This “semiconductor vacuum” is essential for building future quantum computer devices using the quantum spin of millions of implanted atoms with revolutionary capabilities. We have demonstrated long-lived implanted donor atom quantum states in prototype material, made possible by the depletion of background spins in natural silicon and now aim to push the enrichment to greater extremes. We will integrate the extreme material into functional devices that use electrically detected electron spin resonance to probe exceptionally durable quantum states and open a near-term pathway to large-scale devices.Read moreRead less
