Summary
Hybrid nanowire-nanoantenna infrared photodetectors. This project aims to demonstrate room temperature hybrid nanowire-nanoantenna infrared photodetectors by integrating plasmonic nanoantennas on semiconductor nanowire arrays. It is expected that such novel device architectures will not only bring enhanced performance in responsivity, detectivity, and photoresponse bandwidth, but also additional functionalities such as selective wavelength and tunable polarisation, which may significantly outper ....Hybrid nanowire-nanoantenna infrared photodetectors. This project aims to demonstrate room temperature hybrid nanowire-nanoantenna infrared photodetectors by integrating plasmonic nanoantennas on semiconductor nanowire arrays. It is expected that such novel device architectures will not only bring enhanced performance in responsivity, detectivity, and photoresponse bandwidth, but also additional functionalities such as selective wavelength and tunable polarisation, which may significantly outperform current infrared technology. The outcomes will provide a new device platform for next-generation, large-scale, reduced-cost, high-performance imaging systems in self-driving navigation, object identification, spectroscopy, and other high-end defence and civilian applications.Read moreRead less
Brighter than a synchrotron mid-infrared sources for spectroscopy & sensing. This project intends to develop mid-infrared spectroscopy as a powerful diagnostic tool. Mid-infrared spectroscopy allows a light beam to determine the chemical composition of objects or gaseous samples. It has wide applicability — in fields such as medicine, agriculture, the environment, national security and industrial process control — but its use has been hampered by the lack of bright, low-cost sources and integrat ....Brighter than a synchrotron mid-infrared sources for spectroscopy & sensing. This project intends to develop mid-infrared spectroscopy as a powerful diagnostic tool. Mid-infrared spectroscopy allows a light beam to determine the chemical composition of objects or gaseous samples. It has wide applicability — in fields such as medicine, agriculture, the environment, national security and industrial process control — but its use has been hampered by the lack of bright, low-cost sources and integrated devices. This project aims to implement new Australian-made sources that exceed the brightness of even synchrotrons at modest prices. It also aims to demonstrate a single chip integrated version of such a source as the first step towards deployment of mid-infrared technology.Read moreRead less
Physics of a new low power electrothermal radiofrequency plasma thruster. Electric propulsion is the new wave of attitude control for spacecraft. Space engines must be small, lightweight and able to run unattended for over 20 years in a very harsh environment. The physics of a new electrothermal radiofrequency plasma thruster will be investigated. Neutral gas heating will be initially quantified by optical spectroscopy combined with computer generated simulated spectra. A space ready prototype w ....Physics of a new low power electrothermal radiofrequency plasma thruster. Electric propulsion is the new wave of attitude control for spacecraft.

The physics of a new electrothermal radiofrequency plasma thruster will be investigated. Neutral gas heating will be initially quantified by optical spectroscopy combined with computer generated simulated spectra. A space ready prototype will be designed, manufactured and developed to carry out direct measurements of thrust and gas heating in our large space simulation vacuum facility.Read moreRead less
