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
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
Ferroelectric piezoelectric materials and key problems associated with their applications in mechanical, electrical and optical energy transformations. This project aims to investigate the dynamic microstructure of ferroelectric piezoelectric materials in response to electrical fields or mechanical stresses, and therefore identify the factors enhancing the mechanical, electrical and optical couplings for intentional improvement and development of these materials for use in energy transformations ....Ferroelectric piezoelectric materials and key problems associated with their applications in mechanical, electrical and optical energy transformations.
