The Future Industries Institute - FII Seminars are aimed at disseminating key discoveries and fundamental advances across all disciplines of the sciences.
FII Seminars are designed to complement other seminar programs throughout the university, as well as acting as a forum for researchers from across UniSA's various centres and institutes to engage, promote cutting edge research and explore collaborative opportunities.
FII Seminars also aims to bring together our research concentrations with international and national research leaders, to establish and strengthen research relationships, promote the exchange of knowledge and encourage multidisciplinary approaches to tackle issues of strategic importance.
The Functional Materials and Microsystems Research Group harnesses discoveries at the convergence of engineering, materials science, physics, and chemistry to create new functional devices. The Group’s research spans the spectrum of fundamental research to device prototyping in the fields of nanoelectronics, wearable sensors, and optical and terahertz devices. This presentation will present a collection of results from each of these topics.
In nanoscale electronic memories, controlling the concentration of defects and adding selected dopants creates new memory properties. Information can be stored in multiple states beyond just digital 0/1. We have created a new category of high density memories, switching at the scale of 2-4 nm, with significant commercial opportunity while laying the groundwork for hardware-based artificial intelligence.
Overcoming the challenges of integrating high temperature processed oxide thin films and polymer materials creates new opportunities in highly functional wearable sensors. Stretchable, oxide-based patches capable of ultra-violet (UV) sensing and toxic and pollutant gas detection are demonstrated.
Scaling hard–soft integration to the nanoscale allows the realisation of tunable optical devices from gratings to high efficiency, dielectric antennas. At higher frequencies, in the un-tapped terahertz range, materials and their properties have been a major challenge. We have utilised unconventional micro-fabrication techniques to demonstrate tunable metamaterials, high-efficiency absorbers, and dielectric mirrors.
While covering diverse topics, the presentations highlights the potential of oxide materials, elastomers, micro-/nano-fabrication, and the combination of these, along with opportunities for collaboration.
