Nanoscale control of energy and matter for future energy-efficient technologies. Unprecedented control of energy and matter in nanoscale fabrication will be achieved using non-equilibrium self-organised plasma-solid systems. The outcomes will lead to energy-efficient, environment- and human-health-friendly production of nanomaterials for future energy, health, information, food, water, environmental and security technologies.
Nanofabrication of Metamaterials for Next Generation Optical Devices. The dream of invisibility cloaks dates back to ancient times but recent advances in nanotechnology have made this a reality through the use of metamaterials. Metamaterials are artificially-made materials that have optical properties not found in nature. This field is still in its infancy and significant challenges remain and need to be solved before practical applications can be realised.

The dream of invisibility cloaks dates back to ancient times but recent advances in nanotechnology have made this a reality through the use of metamaterials. Metamaterials are artificially-made materials that have optical properties not found in nature. This field is still in its infancy and significant challenges remain and need to be solved before practical applications can be realised. This project builds on Australia’s strategic investment in nanofabrication capabilities to fabricate functional metamaterials and uncover the underlying physical phenomena. It will revolutionise the field of nanophotonics for a variety of novel applications ranging from defence, renewable energy, imaging, sensing to optical communications.Read moreRead less
van der Waals epitaxy for advanced and flexible optoelectronics. This project aims to investigate the growth of compound semiconductors directly on two-dimensional material templates, via the so-called van der Waals epitaxy. Two-dimensional materials combined with compound semiconductors as optoelectronic materials can have many uses. This project expects to design flexible solar cells, which could be integrated with fabrics or building products, and lasers that need small drive currents. It wil ....van der Waals epitaxy for advanced and flexible optoelectronics.

Two-dimensional materials combined with compound semiconductors as optoelectronic materials can have many uses. This project expects to design flexible solar cells, which could be integrated with fabrics or building products, and lasers that need small drive currents. It will use the Anderson localisation effect, a photon management concept, to control the interaction between photons and material and improve device efficiencies.Read moreRead less
III-V semiconductor nanowire solar cells without p-n junctions. This project proposes a new class of nanowire solar cells that do not rely on conventional electrical (p-n) junction for photo-generated charge carrier separation. Instead the band structure of the semiconductors is engineered to form a misalignment which leads to the spatial separation of carriers. This approach is expected to fundamentally change the design of solar cells, eliminating the technologically challenging need for formi ....III-V semiconductor nanowire solar cells without p-n junctions. This project proposes a new class of nanowire solar cells that do not rely on conventional electrical (p-n) junction for photo-generated charge carrier separation. Instead the band structure of the semiconductors is engineered to form a misalignment which leads to the spatial separation of carriers. This approach is expected to fundamentally change the design of solar cells, eliminating the technologically challenging need for forming good electrical junctions, while retaining all advantages inherent to III-V semiconductor nanowire solar cells. More importantly, the device concept proposed is expected to have implications for a wider class of solar cells based on exotic/novel materials or nanostructures where achieving both n- and p-doping may be challenging.Read moreRead less
