Observing atomic-scale structure (AS) is key to unlocking advanced materials science and engineering (MSE).
Aims: We aim to (1) develop software that will enable the accurate observation of atoms in a material, and (2) apply this new software to additive manufactured alloys and quantum computing materials.
Significance: We expect to complete aberration-corrected atom probe tomography capability for the first time internationally. We intend to gain better insights into some longstanding questions in MSE that can only be answered by accurately observing AS.
Benefits: By making the outcomes commercially available, we aspire to improve consistency in the quality of products, and increased yield, that result from manufacturing processes.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
Electrical spin resonance detection techniques for nanotechnology applications. Spin resonance, the science which underpins magnetic resonance imaging, is an extemely useful tool which is currently incompatible with nanotechnology. This project will develop methods to integrate spin resonance techniques and nanotechnology, which will significantly impact both fundamental research and technological advances.

This project aims to establish a transmission electron microscope facility to analyse materials structure at the atomic level. A small number of atoms in critical locations governs the properties of materials from solar cells and catalysts to aerospace alloys, bio-sensors and quantum computers. To understand and engineer matter at this atomic level, tools are needed to characterise these critical atoms. This open access, national facility will be able to characterise matter at the atomic-level. Expected outcomes include better understanding of the natural world and advanced materials to solve problems in energy, technology, health, environment, communications, advanced manufacturing, transport and security.Read moreRead less

This project aims to establish a triple beam ion and electron microscope facility for the modification, preparation and characterisation of materials that have hitherto been too sensitive for high resolution analysis with charged particle beams. It is expected that materials will be studied artefact-free and at the nanoscale with twin ion beams and new detectors that allow novel imaging modes and extreme chemical sensitivity plus controlled atmosphere transfer to other instruments for correlative measurements. This unique facility should benefit research in many disciplines such as physics, chemistry, geology, pharmacy, materials, civil and chemical engineering by allowing first-ever observations of vital phenomena in diverse materials.Read moreRead less
The best of both worlds: electrically detected optical spectroscopy at the single atom limit. One atom, one photon, one electron, in a silicon crystal. We will demonstrate a novel technique to detect the absorption of light by a single atom, in the most significant environment for nanoelectronics and photovoltaics. Our technique will help unravel how light is turned into electricity at the most microscopic and fundamental level.

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
Synthesis of enriched silicon for long-lived donor quantum states. 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 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
