This project will develop next-generation focused ion beam microscopy and nanofabrication using a novel cold ion source based on photoionisation of a laser-cooled atom beam. The low temperature and complex internal state structure of the constituent atoms combine to allow generation of ions with unprecedented brightness and resolution. We will use three unique and innovative ideas: field ionisation of atoms in so-called 'exceptional' states to reduce chromatic aberration; electron-ion correlations to enhance control of the ions at the nanoscale; and atom-atom interactions to isolate and manipulate individual ions. The new technology will enable advances in semiconductor nanofabrication and material characterisation.Read moreRead less

Semiconductor nanowires (NWs) are nanotechnology building blocks that have the potential to transform solar cells, light emitting diodes, lasers and transistors, creating new industries in communications, energy and healthcare. The industrial development of NWs has been blocked by uncertainties in the relationships between their growth conditions, properties and atomic-scale structure. This project will address this challenge by establishing a rigorous framework for these relationships. The project aims to achieve this by harnessing the unique power of atom probe microscopy to reveal the NW structure in three dimensions, and at atomic-resolution. The project aims to place Australian research at the frontier of development of these future industries.Read moreRead less

The development of aberration-corrected electron microscopy, which allows individual atom imaging with unprecedented precision, was recognised by the 2011 Wolf Prize in Physics. However, only a very limited amount of the wealth of information obtainable from such microscopes is currently exploited. By collecting a maximal data set of electrons scattered in manifold different ways and using the fundamental theory of electron-specimen interaction, this project will realise the huge potential of this untapped data. This will improve the utility of scanning transmission electron microscopy far beyond its current level. Applying these new techniques will expand our understanding of the structure and function of advanced materials.Read moreRead less
