Co-doping and transition metal doping of Gallium Nitride. Spintronics is poised to create a new paradigm in device electronics. Gallium nitride (GaN) containing trace amounts of transition metals (such as Fe,Ni) is a promising dilute magnetic semiconductor for spintronics as this material exhibits magnetic behaviour above room temperature. However, the electronic and magnetic properties of these GaN-based semiconductors have not been optimized, as yet.

Gallium nitride (GaN) containing trace amounts of transition metals (such as Fe,Ni) is a promising dilute magnetic semiconductor for spintronics as this material exhibits magnetic behaviour above room temperature. However, the electronic and magnetic properties of these GaN-based semiconductors have not been optimized, as yet. This project aims to establish and test a new growth strategy, know as the co-doping method, for the fabricate of high quality transition metal doped GaN. A broad range of complementary spectroscopic techniques will be used to refine this new fabrication technique.Read moreRead less

Fine Structured Optical Fibre Fabrication - Soot, Rheology and Nanostructure in Modified Chemical Vapour Deposition. For 30 years photonics and telecommunications have relied heavily on optical fibres made by Modified Chemical Vapour Deposition (MCVD), a complex, highly dynamic process with many interacting variables, which is still more art than science. The results are good enough for most purposes but the next generation of photonics demands fibres with intricate, precisely defined internal s ....Fine Structured Optical Fibre Fabrication - Soot, Rheology and Nanostructure in Modified Chemical Vapour Deposition. For 30 years photonics and telecommunications have relied heavily on optical fibres made by Modified Chemical Vapour Deposition (MCVD), a complex, highly dynamic process with many interacting variables, which is still more art than science. The results are good enough for most purposes but the next generation of photonics demands fibres with intricate, precisely defined internal structures. A multi-disciplinary team will elucidate and quantify the exact nature of the fundamental science underlying MCVD - of silicate soot formation, deposition and heat treatment - and translate this into reproducibly fabricated fine structured fibres with high optical and mechanical performance.Read moreRead less
PRODUCTION OF OPTIMAL MICROSTRUCTURED POLYMER OPTICAL FIBRE. Microstructured optical fibres have been described as the 'next generation' of optical fibres, because of their ability to produce tailorisable optical effects. Our success in producing these fibres in polymer was a world-first.

Microstructured optical fibres have been described as the 'next generation' of optical fibres, because of their ability to produce tailorisable optical effects. Our success in producing these fibres in polymer was a world-first. This project will yield a fundamental understanding of the fabrication process, so that for any fibre design the optimal drawing conditions can be determined and maintained for extended draws. This will allow improved draw reproducibility and fibre uniformity so that commercial quality fibres can be produced at economic rates. We will establish quantitative relationships between drawing parameters and optical properties, thus developing optimal designs and production processes.Read moreRead less

Unconventional topological spin structures at the nanometre scale, such as skyrmions in chiral spin systems, could be used in ultra-low energy electronics and high density data storage. In particular, multi-ferroic skyrmion materials could directly control skyrmions through an external electric field, which makes them ideal for nanoelectronics and data storage for IT applications. This project will create and investigate skyrmion materials as the basis for next generation computer and information technology in Australia.Read moreRead less
