This project aims to create a readily accessible facility consisting of a suite of tools to study light-matter interactions in materials, molecules and biological systems. Understanding light-matter interactions offers insight into the properties of nano- and biomaterials. The project intends to combine local probes and pump-probe spectroscopy methods for studying nanoscale femtosecond dynamics. It will be accessible to a broad user base, cementing Australia’s leadership in ultrafast spectroscopy techniques and nano/bio-materials. The facility will provide a window to the quantum nanoworld, with potential for developing new energy efficient light sources, light-harvesting systems and sensors.Read moreRead less
Real-time imaging of crystal strengthening mechanisms in metals. The strength limit of a metal is marked by rapid motion of crystalline defects. The associated speeds can locally approach that of sound. To probe the associated mechanisms clearly requires both spatial and temporal resolution. We propose to create a new bulk x-ray technique with an unprecedented combination of temporal and spatial resolution. We plan to exploit the technique to mediate a step change in modelling strength based on ....Real-time imaging of crystal strengthening mechanisms in metals. The strength limit of a metal is marked by rapid motion of crystalline defects. The associated speeds can locally approach that of sound. To probe the associated mechanisms clearly requires both spatial and temporal resolution. We propose to create a new bulk x-ray technique with an unprecedented combination of temporal and spatial resolution. We plan to exploit the technique to mediate a step change in modelling strength based on twinning. The formation of crystalline twins is known to dictate the strength of the light metal magnesium. A fuller understanding of the effect of twinning on strength in this metal will provide much needed confidence to implement it more widely in energy saving applications.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.

Towards High-quality Hetero-epitaxial III-V Semiconductor Nanowires. The use of semiconductor nanowires has uncovered many scientific curiosities and extended their potential applications in many fields. In general, nanowire growth is governed by metallic catalysts, involving nanowire nucleation and growth. So far, the role of catalysts during nanowire nucleation is not clear and needs urgent attention. This project aims to investigate the behaviour of catalysts before and during the nucleation ....Towards High-quality Hetero-epitaxial III-V Semiconductor Nanowires. The use of semiconductor nanowires has uncovered many scientific curiosities and extended their potential applications in many fields. In general, nanowire growth is governed by metallic catalysts, involving nanowire nucleation and growth. So far, the role of catalysts during nanowire nucleation is not clear and needs urgent attention. This project aims to investigate the behaviour of catalysts before and during the nucleation of III-V nanowires by means of nano-characterisation to ultimately integrate high-quality III-V nanowires on silicon substrates. The new knowledge developed from this project is expected to provide critical insights for developing high-quality III-V nanowires integrated on silicon substrates.Read moreRead less
Exploiting deep sub-surface temperature-induced phase-transformations for an improved approach to semiconductor laser-dicing. This project aims to explore sub-surface laser-induced phase transformations in semiconductors and to exploit this novel method for ultra-fine laser cutting of semiconductor wafers without debris. The outcomes will be understanding new temperature-induced material modifications and innovative technology development relevant for the semiconductor industry.
Understanding, controlling and patterning of ferroelectric domain arrays for advanced device applications. The aim of this project is to understand, fabricate and use patterned ferroelectric domain arrays on the fine scale for advanced materials applications. The resultant domain-patterned technology and processing approaches may significantly impact the development of integrated nonlinear optic devices used in information and communication technology.
