Summary
Development of high performance silicon-based thermoelectrics through band engineering. Thermoelectric (TE) materials, converting waste heat into electricity, have been considered as a sustainable solution to the current energy dilemma. This project aims to realise high-efficiency silicon-based thermoelectrics through rational design of their band structure and nanostructure.

Thermoelectric (TE) materials, converting waste heat into electricity, have been considered as a sustainable solution to the current energy dilemma. This project aims to realise high-efficiency silicon-based thermoelectrics through rational design of their band structure and nanostructure. This will advance the knowledge of maximising the TE performance in silicon-based thermoelectrics and develop new strategies for improving existing TE materials in general. The resulting high performance silicon-based thermoelectrics will greatly promote TE power generation in a more sustainable and environmentally-friendly way, due to their abundance and nontoxicity, benefiting Australia's emerging energy industry, environment and economy.Read moreRead less
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.

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
Towards energy-efficient lighting based on light-emitting diodes: the role of silicon carbide grown on Si Wafers. This project will investigate a potential solution to the problems of cost and quality of light-emitting diodes for solid-state lighting. The expected outcome is knowledge to underpin future development of solid-state lighting that is suitable for a wide replacement of the much less efficient and effective incandescent bulbs and fluorescent tubes.

The project seeks to provide new insights into the effects that structure and composition of catalyst materials have on photocatalytic properties, to tackle the bottlenecks inhibiting the commercialisation of water-splitting technology. The main objective of this project is to strategically design and synthesise highly efficient photo-harvesting mesostructural materials (multi-shelled hollow microspheres) and use them for efficient photocatalytic water splitting. Based on an understanding of photoharvesting materials and the current challenges that plague water-splitting reactions, the project plans to use state-of-the-art materials synthesis and theoretical calculations to develop next-generation photo-harvesting materials for water-splitting systems.Read moreRead less

Bio-inspired conducting peptide nanowires for bioelectronic applications. Some bacteria possess a natural conductive tail constructed from proteins (called a nanowire) that has metal-like conductivity. The electrical signals in these nanowires are carried through aromatic groups in the peptides and/or attached cytochromes.

The electrical signals in these nanowires are carried through aromatic groups in the peptides and/or attached cytochromes. This project addresses the design and assembly of conducting peptide-based fibrils inspired by these nanowires. It has already been shown that peptides can, by design, self-assemble into long thermostable fibrils that support cell growth and development. The project’s goal is now to create cost-effective, non-toxic, conducting peptide fibrils that can be used in water or physiological environments for bioelectronics applications.Read moreRead less

Transformational lighting: changing the way we live. This Fellowship aims to advance the science of ultrathin efficient lighting technologies based on low embedded energy organic light-emitting diodes (OLED). By creating innovative semiconductor materials and diode architectures that optimise each step in light generation—from charge injection, transport and capture to light emission—the project aims to deliver transformative OLED lighting that is more efficient than standard fluorescents by 50%. The intended outcomes of the project are design rules for OLED componentry, including thin, flexible architectures for deployment in a range of environments.
