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.

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

This project aims to explore strategies to optimise the magnetisation and Curie temperature by incorporating dopants via ion implantation, and exploiting proximity effects in heterostructures with magnetic thin films. The recently discovered magnetism in topological insulators opens up a new class of materials with potential applications in energy-efficient electronics, data storage and information processing. The central challenges are to control the underlying magnetic structure and stabilise magnetic order at desirable temperatures. The project expects to discover new composite materials and advance our knowledge for designing magnetic components in the next generation of electronics with ultra-low power dissipation.Read moreRead less
Electro-mechanics of natural load-bearing materials: understanding mechanisms of toughening, remodelling, and self-healing. Nature provides some of the most advanced functional structural materials, with the capability to remodel and strengthen under changing loads. The origins of the functional properties which allow them to do this will be explored, providing the possibility of developing materials which mimic this behaviour.

'Designer defects' - A new approach to functional oxide interfaces. The conventional approach to metal oxide interfaces is 'perfection at all costs' with growth tuned to minimise defects and unwanted chemical intermixing. This project aims to turn this approach on its head by creating interfaces with 'designer defects' that become the critical portion of a functional device.

The conventional approach to metal oxide interfaces is 'perfection at all costs' with growth tuned to minimise defects and unwanted chemical intermixing. This project aims to turn this approach on its head by creating interfaces with 'designer defects' that become the critical portion of a functional device. This project proposes that one can promote functionality by making use of new physical properties that arise from the deliberate introduction of structural and electronic mismatches at an interface. Such purposely induced 'designer defects' in epitaxial oxide thin films will allow new properties to be achieved in nanoscale layers. This is expected to lead to a new class of functional materials to be used in sensors and nanoelectronics.Read moreRead less
