Infrared sensors and systems are finding increasing use in Australia's core industries: particularly defence, mineral exploration, environmental monitoring, precision agriculture, homeland security, and medical diagnostics. Due to the reduced cooling requirements, the Infrared detector structures to be investigated in this project have the potential to deliver high performance infrared technology at a significantly lower cost and, hence, widening its applications. The new science proposed in this project, and new technological knowledge expected from its application, will allow Australian researchers to participate and significantly contribute to the international effort in this field and to exploit any developed intellectual property.

Development of inert gas ion beams for fabrication of nano-structures. This project will develop a high brightness, high density ion beam for reactive fabrication of structures with dimensions of the order of and less than 100 nano-metres. Present systems use liquid metal ion sources which can pollute the substrates being fabricated. Use of inert gas ions will overcome this problem and lead to a new type of ion source to replace the older systems. Added advantages include significantly increased ....Development of inert gas ion beams for fabrication of nano-structures. This project will develop a high brightness, high density ion beam for reactive fabrication of structures with dimensions of the order of and less than 100 nano-metres. Present systems use liquid metal ion sources which can pollute the substrates being fabricated. Use of inert gas ions will overcome this problem and lead to a new type of ion source to replace the older systems. Added advantages include significantly increased lifetime much higher reproducibility. Our commercial collaborator, FEI Company, estimate the world market as being $US100,000,000 and will actively promote this technology worldwide when it is fully developed.Read moreRead less
Novel silicon photonic devices harnessing new leakage behaviour. The continuing advance of microprocessor performance requires vast quantities of data to be transferred between on-chip processor cores and to the outside world. The transfer of data via metal wires cannot meet this demand due to limited bandwidth and astonishing heat generation. Low-loss photonic transport integrated onto the silicon chip offers a solution. With this project we will explore harnessing a newly discovered phenomenon ....Novel silicon photonic devices harnessing new leakage behaviour. The continuing advance of microprocessor performance requires vast quantities of data to be transferred between on-chip processor cores and to the outside world. The transfer of data via metal wires cannot meet this demand due to limited bandwidth and astonishing heat generation. Low-loss photonic transport integrated onto the silicon chip offers a solution. With this project we will explore harnessing a newly discovered phenomenon in silicon photonics to achieve devices such as electrically pumped lasers and wavelength routers. The project will collaborate closely with researchers in the USA, but will focus on research of designs that can be created in Australia and licensed to major industry across the globe.

Microprobing of Crystal Polarisation in Polycrystalline Compound Semiconductors. We will improve the quality of polycrystalline compound semiconductor thin films, grown by chemical vapour deposition. The novelty of the project is divided between applying new methods to assess film quality and deposition development. An expected outcome will be a measurement system with the unique capability of probing the spatial variation of dielectric polarisation with sub-micron resolution. Polycrystalline ....Microprobing of Crystal Polarisation in Polycrystalline Compound Semiconductors.

The novelty of the project is divided between applying new methods to assess film quality and deposition development. An expected outcome will be a measurement system with the unique capability of probing the spatial variation of dielectric polarisation with sub-micron resolution. Polycrystalline GaN recently been taken to state of the art performance at Macquarie University, will be the trial material. The information obtained will inform material improvement, with the ultimate aim of fabricating polycrystalline, GaN-based transistors and blue light-emitting diodes on glass substrates.Read moreRead less
