Summary
A novel graphene-based optical sensing platform. Graphene has extraordinary electronic and optical properties as well as large specific surface area which afford great potential for sensor applications. This project will develop an innovative sensing platform to bring graphene related materials and devices a step closer to practical applications, particularly in biochemical sensors.
Three dimensional nano-lithography: combined electron and ion beam fabrication. By adding one more dimension to a planar (hence two dimensional - 2D) lithography, it will become possible to structure and texture materials in three dimensions (3D) by combining electron beam lithography (2D) and ion beam milling (3D) with the highest precision of several nanometres. This will open new applications in photonics and sensing.

Image correlation spectroscopy on gold nanorod based plasmonic random media for nanophotonic applications. The push for high capacity storage and high speed plasmonic switching beyond terahertz (THz) is continuing, but the question remains whether this limit can be overcome. This project tackles these issues using plasmonic random media, which will help realise the elusive terabyte storage capacity and THz switching speed.
Indistinguishable Quantum Emitters in van der Waals Materials. Solid state sources of single photons ("quantum emitters") are a key building block for implementation of scalable quantum technologies. Amongst many potential platforms studied, impurities in hexagonal boron nitride (hBN) are at the forefront due to their brightness and ease of manufacturing. However, their main disadvantage is spectral instability which prohibits engineering of practical devices.

Amongst many potential platforms studied, impurities in hexagonal boron nitride (hBN) are at the forefront due to their brightness and ease of manufacturing. However, their main disadvantage is spectral instability which prohibits engineering of practical devices. The current project will address this bottleneck and deliver an optically stable solid state quantum light source in hBN. The project will produce a robust hardware toolkit for quantum technologies. It will provide excellent training for young Australians and generate key intellectual property for quantum startups and the quantum industry.Read moreRead less

Plasmonic nanofocusing for super-resolution DNA imaging. Plasmonics (waves in a metal's electrons) can focus light to extreme concentrations that enable imaging techniques to resolve features well beyond the optical barrier known as the diffraction limit.

Plasmonics (waves in a metal's electrons) can focus light to extreme concentrations that enable imaging techniques to resolve features well beyond the optical barrier known as the diffraction limit. This project aims to develop a routine methodology capable of extracting precise information from single DNA molecules by incorporating plasmonic components into a lab-on-a-chip device for use under conventional optical microscopes. The configuration would have the convenience and technological maturity associated with microscopes whilst being able to capture details of biomolecules with unprecedented detail. New DNA analyses will be made possible by the platform, such as studying the genomic diversity within a population of tumour cells.Read moreRead less
