Model reduction is an important area of study in the analysis and design of dynamical systems. Its objective is to obtain a low-order model given a high-order system model such that the low-order model closely approximates the input-output behaviour of the original high-order system. Although theory and application of model reduction is well developed, there are many unresolved issues such as efficient model reduction techniques for large-scale circuit simulation and communication applications, frequency-weighted model reduction techniques for controller-design applications, and error bounds for the reduction techniques. The project aims to address these issues.Read moreRead less

The ability of infrared detectors to directly sense the thermal output of an object has applications in medicine, search and rescue, bushfire detection and in the defence and surveillance industries. The highest performing infrared detectors are photon detectors based molecular beam epitaxy (MBE) grown HgCdTe. The primary aims of this project relate to the fundamental understanding of p-type doping in MBE grown HgCdTe, a current and major difficulty in HgCdTe technology, and the use of such p-type MBE grown layers in conjunction with a newly developed plasma process based n-p junction formation technology to realise novel and innovative infrared detector structures. Such structures would have the ability to revolutionise the use of HgCdTe in infrared detectors and focal plane array applications.Read moreRead less

Dark current and noise mechanisms in nBn HgCdTe infrared detectors. Novel mercury cadmium telluride (HgCdTe) nBn (two n-type semiconductors sandwiching a barrier layer) infrared (IR) detectors are theoretically capable of operating at higher temperatures than conventional IR detectors.

Novel mercury cadmium telluride (HgCdTe) nBn (two n-type semiconductors sandwiching a barrier layer) infrared (IR) detectors are theoretically capable of operating at higher temperatures than conventional IR detectors. Their reduced cooling requirements lead to reductions in the size, weight and power of IR imaging systems without loss in IR detection performance. Unfortunately, HgCdTe nBn detectors are currently affected by non-ideal dark current and noise levels whose physical origins and nature are poorly understood. The proposed experimental and theoretical investigations and optimisations are anticipated to minimise such non-idealities and thus enable the demonstration of HgCdTe nBn IR detectors capable of revolutionising portable IR detection systems for security and rescue applications.Read moreRead less

Water recycling is becoming critical for water supplies worldwide, due to declining natural supplies of fresh water, combined with increasing demand. The greatest community and industry concerns over recycled water are quality assurance and relative cost. Ensuring quality requires monitoring of contaminants, yet no single real-time technology exists to measure the myriad of potential contaminants. This project will develop technology using AlGaN/GaN-based transistors, sensitised to different contaminants, enabling multi-analyte real-time sensor arrays. In situ monitoring systems based on such arrays will be fast, accurate, reliable, low-cost, and applicable to a broad variety of water recycling projects.Read moreRead less
