Summary
Deterministic coherent diffractive imaging for the nanosciences. The technological trend towards nanoscale device fabrication demands picoscale measurements which will only be possible with the development of novel and advanced imaging techniques. This project will develop and implement cutting edge approaches to lensless imaging using both electrons and x-rays and will enable real-time imaging at the picoscale.
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
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. By collecting a maximal data set of electrons scattered in manifold different ways and using the fundamental theory of electron-specimen in ....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. 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
Imaging light elements, dopants and vacancies. This project will pioneer techniques for seeing light atoms, such as oxygen in superconductors and lithium in lithium battery materials. Coming to understand the function of light elements in advanced materials is vital as such materials play a pivotal role in meeting the pressing challenges that beset us in energy management.

Summary
Nano-resolution hard x-ray diffraction imaging with conventional laboratory sources. The project will combine advanced optics and algorithms for diffraction imaging to develop a desktop hard x-ray microscope. The system will display ultra-high resolution and will be highly complementary to electronic and optical microscopies for diverse applications in materials engineering, nanofluidics and cell biology.

Locating Atoms by Observing Crystallographic Phase. Atomic structures are determined by measuring how they scatter radiation. However half of the necessary information, the crystallographic phase, cannot be measured from the scattered intensity. For a century the only option has been to deduce the phase via the statistical analysis of thousands of intensity measurements. This project aims to develop a method to determine atomic structures from the direct observation of phase. From a handful of o ....Locating Atoms by Observing Crystallographic Phase. Atomic structures are determined by measuring how they scatter radiation. However half of the necessary information, the crystallographic phase, cannot be measured from the scattered intensity. For a century the only option has been to deduce the phase via the statistical analysis of thousands of intensity measurements. This project aims to develop a method to determine atomic structures from the direct observation of phase. From a handful of observations and no formal measurements, atoms can be located with picometre precision. It is predicted that this method will be direct, rapid and unequivocal, sensitive to light atoms and applicable to nanostructures, which will represent a paradigm shift in crystallography.Read moreRead less
