Novel advances in sub-nanometer imaging. After two decades of research the first wave of applications in nanotechnology and nanobiology is breaking. Immediately key to further progress in both areas is the ability to characterise the structure of such systems and also their evolution on very short time scales. This research project places Australia at the forefront in this endeavour.
Foundation studies of ion-beam nanotechnology. The impact of a single fast atom with sensitive materials leaves a path of latent damage with a diameter of around 10 nm. This latent damage can be developed to create nanostructures in a novel technique called ion beam nanomachining. We propose to create a method for using single atom impacts to produce nanomachined structures with novel physical and optical properties. This will be done by use of an active substrate that functions as a detector s ....Foundation studies of ion-beam nanotechnology.

Photoemission studies of Fermi surfaces, of wide bandgap semi-conductors and quasi crystals. Knowledge of the detailed shape of the Fermi surface of a conducting material is vital for an understanding of its electrical and magnetic properties. We will use angle resolved photo-emission in conjunction with synchrotron radiation to explore the Fermi surfaces of technologically important magnetic alloys, the mechanism driving the occurance of charge density waaves in layer compounds and the electron ....Photoemission studies of Fermi surfaces, of wide bandgap semi-conductors and quasi crystals. Knowledge of the detailed shape of the Fermi surface of a conducting material is vital for an understanding of its electrical and magnetic properties. We will use angle resolved photo-emission in conjunction with synchrotron radiation to explore the Fermi surfaces of technologically important magnetic alloys, the mechanism driving the occurance of charge density waaves in layer compounds and the electronic properties of wide band-gap semi-conductors such as GaN, SiC and of selected quasi crystals. These measurements will be performed using a unique high resolution toroidal spectrometer currently under construction at La Trobe university.Read moreRead less

Diamond Quantum Dots Fabricated By Ion Implantation. For centuries scientists have been fascinated by the 'alchemy' of transforming carbon into diamond. This project aims to fabricate diamond nanocrystals embedded in a glass matrix by direct carbon ion implantation followed by thermal annealing. Unlike other methods of making diamond, the coalescence of carbon into diamond occurs under heating in a conventional furnace and does not require the application of high external pressures or any pre-ex ....Diamond Quantum Dots Fabricated By Ion Implantation. For centuries scientists have been fascinated by the 'alchemy' of transforming carbon into diamond. This project aims to fabricate diamond nanocrystals embedded in a glass matrix by direct carbon ion implantation followed by thermal annealing. Unlike other methods of making diamond, the coalescence of carbon into diamond occurs under heating in a conventional furnace and does not require the application of high external pressures or any pre-existing diamond template. We outline a scheme to exploit the properties of these crystals for novel applications in quantum devices.Read moreRead less

The goal of quantum computing research is to harness the properties of quantum mechanics to build computers that are exponentially more powerful than the computers of today. Along the way, many spin-off technologies for conventional computing and nanotechnology are expected.
