Novel Silicon-Based Photonic Devices. Silicon's pre-eminence in high-speed digital electronics does not extend to optoelectronics where the demand is for devices that can generate, guide, detect and process light. However, the properties of silicon are dramatically altered when it is reduced to nanometre dimensions.

Silicon's pre-eminence in high-speed digital electronics does not extend to optoelectronics where the demand is for devices that can generate, guide, detect and process light. However, the properties of silicon are dramatically altered when it is reduced to nanometre dimensions. Advances in the understanding of such effects and in the fabrication and application of nanoscale silicon have provided the prospect of new and innovative Si-based photonic devices, and of fully integrated electronic and photonic functionality. This project aims to extend the understanding of nanoscale silicon and to develop and prototype novel Si-based photonic devices based on this material.Read moreRead less
The Physical and Optical Properties of Self-Assembled Si Nanocrystals. The properties of nano-scale materials can differ significantly from those of their bulk counterparts. As such, they can provide materials with new and novel properties as well as proving a useful test of modern theories.

Formation of nanocrystals (or nanocrystals with core/shell structure) and applications for photonics, floating gate and magnetic memory. Materials that contain nanometre-sized crystallites of a second material can exhibit novel optical, electrical and magnetic properties that have direct technological application.

Materials that contain nanometre-sized crystallites of a second material can exhibit novel optical, electrical and magnetic properties that have direct technological application. However, it is often difficult to control the size and concentration of the small crystals using conventional synthesis techniques. This project will overcome these limitations by exploiting the unique properties of pulsed-laser heating to produce the crystals. It will also investigate the optical, electrical and magnetic properties of these new materials and asses their suitability for super-dense data storage, solid-state lighting and advanced detection systems.Read moreRead less

This project aims to investigate radical new approaches to reduce chemical and energy requirements for transformation of indigenous natural graphite to a high-value material graphene. The graphite which will be used is the by-product of the Uley mines of South Australia. Graphene is an atomically thin arrangement of carbon atoms with combinations of remarkable chemical inertness, strength, and massive surface area. Utilising fluid phase dispersed graphene, this project aims to develop scalable and industrially-adaptable methods to manufacture thin yet mechanically robust, inert, fouling-resistant, highly-permeable graphene-based asymmetric membranes. These advanced membranes are expected to find wide application in reducing discharge of mining effluents and recovery of precious metals.Read moreRead less

Wire bonding is an essential step for making the contacts of any micro device with external power supply or signal conditioning circuitry. The contact pads for such devices vary in size from 0.050 mm x 0.050 mm to few 100s of micrometers. The proposed facility will be required for making contacts either using thermal or ultrasonic methods with complete automatic stages. The electrical contacts are used to drive or monitor MEMS, Polymer micro devices and nano- fluidic systems. This facility will be used for different applications including photonics and communication devices (RMIT), flexi circuits and microwave devices (DSTO) and micro/nano fluidic systems (SUT).
