This project aims to develop technologies to fabricate advanced electronic materials based on gallium antimonide (GaSb), to explore their physics and use them in improved optoelectronic devices.
GaSb technology is in its infancy, therefore basic and applied research is needed to utilise these materials to their full potential for long wavelength photonic devices with unique promise in military and civilian applications: fire detection, missile and surveillance systems, environmental monitoring, biology and medicine.
As an outcome, growth protocols for innovative device structures will be established, the structures' behaviour assessed and device fabrication and characterisation carried out and reported.

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.

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
Development of a Novel and Quantitative Approach to Phase Imaging with Applications to Functional Nanomaterials. This project will improve and apply an innovative approach to obtaining phase information from electron microscopy images, currently being commercialised by IATIA Ltd. We will develop the approach so that it is fully quantitative, even at the nanoscale, and explore the effect of experimental parameters such as beam coherence, aberrations, specimen contamination and diffraction.

This project will improve and apply an innovative approach to obtaining phase information from electron microscopy images, currently being commercialised by IATIA Ltd. We will develop the approach so that it is fully quantitative, even at the nanoscale, and explore the effect of experimental parameters such as beam coherence, aberrations, specimen contamination and diffraction. We will apply the method to both physical and molecular nanomaterials, including a new class of self-organising molecules. Phase imaging can visualise the structures, polarities, charge and conductivity distributions in these materials and so assist in the development of new materials and devices.Read moreRead less
Scaling-up microstructured fibres for terahertz radiation. Terahertz radiation is the last region of the electromagnetic spectrum to be fully utilised. Many applications have been identified but their practicality has been limited by a lack of low-loss flexible waveguides. The waveguides to be developed in this project will build on Australia's existing international lead and investments in photonics as well as extend the dynamic field of microstructured optical fibres, indentified as the 'futur ....Scaling-up microstructured fibres for terahertz radiation. Terahertz radiation is the last region of the electromagnetic spectrum to be fully utilised. Many applications have been identified but their practicality has been limited by a lack of low-loss flexible waveguides. The waveguides to be developed in this project will build on Australia's existing international lead and investments in photonics as well as extend the dynamic field of microstructured optical fibres, indentified as the 'future' of optical fibres. Low-loss flexible waveguides will enable imaging and spectroscopy applications that can reveal and object's internal structure and composition. This will have immediate applications in security, quality control, medical imaging and other safety or industrial applications.Read moreRead less

Mapping electronic structure and material properties with atomic resolution. This project will use electron energy loss spectroscopy (EELS) to map the bonding and electronic structure of InGaN quantum wells at the atomic scale. We will measure and correlate the local composition, strain and electronic structure variations within the wells in order to understand the optical emission in this system.

Super-resolution in microscopy and optical recording. The classical resolution limit imposes severe restrictions on the performance of optical instruments, especially in optical microscopy and optical recording. Improved understanding of the fundamental principles involved in super-resolution should allow substantial increases in resolution to be achieved. We aim to explore theoretically and experimentally the performance of different super-resolution schemes alone and in combination, including ....Super-resolution in microscopy and optical recording. The classical resolution limit imposes severe restrictions on the performance of optical instruments, especially in optical microscopy and optical recording. Improved understanding of the fundamental principles involved in super-resolution should allow substantial increases in resolution to be achieved. We aim to explore theoretically and experimentally the performance of different super-resolution schemes alone and in combination, including optical masks, near-field optics, detector arrays, multi-photon imaging and digital deconvolution. Selected methods will be demonstrated with practical examples in multi-photon microscopy. Applications in super-high density optical recording will also be studied.Read moreRead less

Australian economic growth will depend increasingly on the provision of devices using materials designed at the molecular level. Scanning probe microscopy, which uses tips placed very close to surfaces to analyse or modify the surfaces with molecular precision, is an indispensible tool in designing such materials. In this project, scanning probe microscopy will be used to analyse and build structures on polymer solar cells in order to maximise the efficiency of the cells and build prototype nanoscale polymer devices.
