Atomic-Scale Identification of Amorphization and Relaxation Processes in Compound Semiconductors. We seek a fundamental understanding of the processes that govern implantation-induced structure, at the nanometer scale, in the compound semiconductors used in photonic device fabrication.

We seek a fundamental understanding of the processes that govern implantation-induced structure, at the nanometer scale, in the compound semiconductors used in photonic device fabrication. Since implantation-induced disorder limits the performance of such devices, the proposed project is of substantial technological significance and national benefit. The Photon Science techniques of perturbed angular correlation and extended x-ray absorption fine structure spectroscopy will be used to identify the mechanism of amorphisation and relaxation in order to enable more effective exploitation of compound semiconductors in advanced telecommunications systems.Read moreRead less

The effect of stress on the production and evolution of defects in ion-implanted silicon. This project aims to improve the reliability of semiconductor devices by understanding how stresses created within the device during processing affect the formation and migration of defects, and by using this information to improve device modelling and process simulation.
Towards phase, composition and homogeneity control in ternary nanowires. Semiconductor nanowires have enormous potential for large scale industry manufacturing as each individual nanowire represents one device. The aim of this project is the catalyst-free growth of ternary nanowires with control over structure, composition and homogeneity within the wire. Detailed electron microscopy analyses are essential to reconstruct a three-dimensional view of the nanowires and understand the growth mechani ....Towards phase, composition and homogeneity control in ternary nanowires. Semiconductor nanowires have enormous potential for large scale industry manufacturing as each individual nanowire represents one device. The aim of this project is the catalyst-free growth of ternary nanowires with control over structure, composition and homogeneity within the wire. Detailed electron microscopy analyses are essential to reconstruct a three-dimensional view of the nanowires and understand the growth mechanism at work. These structural characteristics determine the optical properties. It is expected that precise control over growth will allow the emission wavelength of the nanowires to be tuned and allow their use in optoelectronic device structures. Two innovative techniques are proposed using strain and patterned substrates for ternary nanowire growth.Read moreRead less

We will develop a new way for laboratory synthesis of new classes of super-hard and super-dense materials at and above the extremely high temperature and density range currently accessible only in nuclear explosions. The ability of ultra-fast laser-induced phase transformations will be exploited aiming to form materials with exotic properties, which are theoretically predicted, but has not experimentally confirmed yet. Our new approach will have a profound interdisciplinary impact.

Optical-spin coupling in the nitrogen-vacancy centre in diamond. Australia has made investment in the developing area of quantum information processing where information is stored and processed by manipulating the spin states in solids. One of the most promising materials for this purpose is diamond incorporating nitrogen-vacancy colour centres. The appeal with this material is that the processing can be faster and components smaller as the spins can be controlled by laser beams.
