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
Making every electron count in atomic resolution microscopy. The development of aberration-corrected electron microscopy, which allows individual atom imaging with unprecedented precision, was recognised by the 2011 Wolf Prize in Physics. However, only a very limited amount of the wealth of information obtainable from such microscopes is currently exploited.

The development of aberration-corrected electron microscopy, which allows individual atom imaging with unprecedented precision, was recognised by the 2011 Wolf Prize in Physics. However, only a very limited amount of the wealth of information obtainable from such microscopes is currently exploited. By collecting a maximal data set of electrons scattered in manifold different ways and using the fundamental theory of electron-specimen interaction, this project will realise the huge potential of this untapped data. This will improve the utility of scanning transmission electron microscopy far beyond its current level. Applying these new techniques will expand our understanding of the structure and function of advanced materials.Read moreRead less

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 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

Precise atomic-scale structure determination in thick nanostructures. This project aims to tackle a great challenge of atomic-scale characterisation: quantitative structure determination. Powerful new electron microscopes offer a window into the atomic world, but complex electron multiple scattering has limited reliable structure determination to ultrathin materials.

This project aims to tackle a great challenge of atomic-scale characterisation: quantitative structure determination. Powerful new electron microscopes offer a window into the atomic world, but complex electron multiple scattering has limited reliable structure determination to ultrathin materials. This project expects to overcome this barrier. Anticipated outcomes include methods that use the latest detector technology to determine structure and interatomic bonding in much thicker nanostructures than hitherto possible. This should benefit academic and industrial researchers by giving them new tools to understand and design high-performance materials for applications ranging from catalysis to energy storage to next-generation electronics.Read moreRead less
