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 expects to overcome this barrier. Anticipated outcomes include methods that use the latest detector technology to det ....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 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

Summary
An analytical transmission electron microscope for the investigation of functional materials, earth processes and novel condensed matter. Sustainablity depends on the delivery of clean energy, pristine water and air, and the manufacture of consumer products with small environmental footprints. Modelling long-term impacts requires an understanding of the hydro-geological cycles. The technologies are well known—efficient electronics, fuel cells, lightweight composites, and so on—but delivery is ....An analytical transmission electron microscope for the investigation of functional materials, earth processes and novel condensed matter. Sustainablity depends on the delivery of clean energy, pristine water and air, and the manufacture of consumer products with small environmental footprints. Modelling long-term impacts requires an understanding of the hydro-geological cycles. The technologies are well known—efficient electronics, fuel cells, lightweight composites, and so on—but delivery is not straightforward. It is clear, however, that novel materials manipulated at fine scales will be key. Transmission electron microscopy (TEM) guides the development of sustainable technologies. The new TEM facility at ANU will accelerate current studies, by enhancing the materials research portfolio, and extending national and international collaborations in materials, geological and earth sciences.Read moreRead less
Imaging Symmetry – A New Mechanism for Revealing the Structure of Matter. This project aims to develop a revolutionary method for imaging atomic structures. In this method, the image contrast derives from the symmetry of the structure, measured at the picometre scale, using tiny electron probes. This new conceptual approach is expected to overcome some of the key limitations of existing electron microscopy methods by providing increased sensitivity and reduced radiation damage, thereby enabling ....Imaging Symmetry – A New Mechanism for Revealing the Structure of Matter. This project aims to develop a revolutionary method for imaging atomic structures. In this method, the image contrast derives from the symmetry of the structure, measured at the picometre scale, using tiny electron probes. This new conceptual approach is expected to overcome some of the key limitations of existing electron microscopy methods by providing increased sensitivity and reduced radiation damage, thereby enabling complex structures in technologically important materials to be determined. This should provide new ways to understand the properties of these materials advanced materials and engineer them for applications in the energy, transport, health, communications and other sectors of society.

Hot Topic: Quantum Design of Phononic Heat Filters. Heat management is critical to many technologies for sustainable energy, electronics, protective equipment and energy-efficient buildings. The phonon is the quantum particle representing a travelling vibration and is responsible for the transmission of heat in solids.

Heat management is critical to many technologies for sustainable energy, electronics, protective equipment and energy-efficient buildings. 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
Novel advances in sub-nanometer imaging. After two decades of research the first wave of applications in nanotechnology and nanobiology is breaking. Immediately key to further progress in both areas is the ability to characterise the structure of such systems and also their evolution on very short time scales. This research project places Australia at the forefront in this endeavour.

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.
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.
