STRUCTURAL ANALYSIS OF SILICON ON SAPPHIRE THIN FILMS GROWN USING SOLID-PHASE EPITAXIAL TECHNIQUES. Devices based on silicon-on-sapphire processing are potentially faster and are prepared with fewer processing steps than those based on conventional silicon processing technology. However, silicon-on-sapphire films prepared by traditional methods are unsatisfactory due to the high densities of defects they contain.

Devices based on silicon-on-sapphire processing are potentially faster and are prepared with fewer processing steps than those based on conventional silicon processing technology. However, silicon-on-sapphire films prepared by traditional methods are unsatisfactory due to the high densities of defects they contain. The development of solid phase epitaxial processing has lead to significant increases in performance. This project will characterize the structures of films grown by this new process, and relate them to both the processing conditions and device performance. A greater understanding of the relationship between processing, structure and properties will assist the commercial development of these devices.Read moreRead less
Optical fibre devices for sideways delivery of laser light during keyhole surgery. Mulitmode optical fibres are typically used to deliver high power laser light which is emitted from the end of the fibre to irradiate tissue during surgery. For intravenous delivery of laser light in the treatment of cardiac fibrillation (heart flutter) we require a sideways-directed illuminating beam. However reliable methods of delivering high power laser light in a sideways-directed beam are not currently avai ....Optical fibre devices for sideways delivery of laser light during keyhole surgery. Mulitmode optical fibres are typically used to deliver high power laser light which is emitted from the end of the fibre to irradiate tissue during surgery. For intravenous delivery of laser light in the treatment of cardiac fibrillation (heart flutter) we require a sideways-directed illuminating beam. However reliable methods of delivering high power laser light in a sideways-directed beam are not currently available. Using the ultraviolet laser fibre processing expertise already developed at Macquarie University, we propose to develop and characterise novel fibre-based devices which would allow controllable delivery of light sideways.Read moreRead less

Synthetic polymeric insulation has proved very successful in high voltage alternating current power transmission cables, and cable manufacturers have therefore sought to use it in high voltage direct current (HVDC) cables, for which there is a rapidly growing demand. Yet the accumulation of space charge in such cables presently severely limits the maximum operating voltage and transmitted power. Nearly all this space charge is due to the temperature gradient in the insulation. We will analyze space charge profiles in polyethylene and other synthetic polymers, and derive basic scientific data which will inform the design of HVDC cables with greatly enhanced performance.Read moreRead less
