Transistor-based sensor technology for fast, reliable and accurate in situ monitoring of recycled wastewater. 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.

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
Ion-beam synthesis of functional oxides for next generation memory devices. This project seeks to explore a low-temperature approach to stoichiometry control using direct oxide synthesis and defect-engineering based on ion-implantation, a routine semiconductor fabrication process. This has the potential to improve device manufacturability and functionality. In thin film form, transition metal oxides can be subjected to intense electric fields and exhibit characteristic resistance changes suitabl ....Ion-beam synthesis of functional oxides for next generation memory devices. This project seeks to explore a low-temperature approach to stoichiometry control using direct oxide synthesis and defect-engineering based on ion-implantation, a routine semiconductor fabrication process. This has the potential to improve device manufacturability and functionality. In thin film form, transition metal oxides can be subjected to intense electric fields and exhibit characteristic resistance changes suitable for non-volatile memory applications. However, their electrical response depends critically on stoichiometry and this must be precisely engineered for optimal device performance. This project aims to develop next-generation memory devices as a replacement for current flash memory. The proposed technology uses resistance changes in functional-oxides to store information, and offers the potential for smaller and faster memory.Read moreRead less
