Unravelling the structural origin of cyclic fatigue in ferroelectrics. Ferroelectric materials have extensive applications in electromechanical devices and memories and in service are often subjected to repeat mechanical and/or electrical loading, leading to cyclic fatigue and failure. This project aims to apply in-situ electron microscopy techniques and computational modelling to explore cyclic ferroelectric fatigue behaviour and to understand the relationships between local atomic scale struct ....Unravelling the structural origin of cyclic fatigue in ferroelectrics. Ferroelectric materials have extensive applications in electromechanical devices and memories and in service are often subjected to repeat mechanical and/or electrical loading, leading to cyclic fatigue and failure. This project aims to apply in-situ electron microscopy techniques and computational modelling to explore cyclic ferroelectric fatigue behaviour and to understand the relationships between local atomic scale structure and fatigue. The structural origin of ferroelectric fatigue has not been clear because of the limitations of previous measurement capabilities. This project will provide guidance in materials design to increase ferroelectric fatigue lifetime for more reliable ferroelectric-based electronic devices.Read moreRead less

This project aims to establish an in situ transmission electron microscope that will allow the atomic scale imaging of materials, while simultaneously measuring physical, chemical, electrical and optical properties, using a novel combination of cutting edge in-situ sample holders and an instrument mounted laser system. The instrument will be optimised for imaging of dynamic phenomena and the combination of spatial resolution in the picometre scale, with microsecond level temporal resolution will be unique. The instrument will accelerate research into hydrogen production and carbon dioxide transformation, and thus support Australia's move to a more sustainable economy. Read moreRead less

Xe-plasma dual beam for advanced future materials. This project aims to establish a state of the art Xe-Plasma dual-beam facility providing characterisation and fabrication capabilities to Australia’s research community. The project will use two beams - one Xe, the other electrons - to mill the surface of bulk materials which are subsequently analysed by electron or ion beam techniques to determine atomic-scale microstructure(s) and compositions.

This project aims to establish a state of the art Xe-Plasma dual-beam facility providing characterisation and fabrication capabilities to Australia’s research community. The project will use two beams - one Xe, the other electrons - to mill the surface of bulk materials which are subsequently analysed by electron or ion beam techniques to determine atomic-scale microstructure(s) and compositions. Anticipated outcomes are advanced materials engineering and new knowledge about ancient and future materials. This is expected to provide significant advances across a variety of fields including material science, engineering and geology and enhance trans-disciplinary collaborations.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
