This project will investigate the use plasmonic absorption of light in metal nanostructures to activate the selective oxidation/reduction of a gas molecule on a semiconductor nanoparticle. This concept will be used with the aim of developing a sensing technique capable of measuring ultra-low concentrations (ppb) of breath markers for lung cancer detection. It is expected that porous sensing films of semiconductor and metal nanoparticles with well-defined light absorption properties will be fabricated. Superior selectivity will be achieved by matching the wavelength of the absorbed light with the required activation energy for oxidation/reduction. Successful outcomes will enable multi-analyte fingerprint identification by on-chip devices with applications ranging from portable medical diagnostics to national security.Read moreRead less

Two-Dimensional Material Tandem Detectors for Polarimetry and Spectroscopy. The aim of this project is to leverage the fundamental advantages that two-dimensional (2D) materials could provide to vertically-stacked (tandem) photodetectors. The strong absorption, tunable bandgap and polarisation dependence that many 2D materials exhibit, provides a means by which to detect properties of light.

The aim of this project is to leverage the fundamental advantages that two-dimensional (2D) materials could provide to vertically-stacked (tandem) photodetectors. The strong absorption, tunable bandgap and polarisation dependence that many 2D materials exhibit, provides a means by which to detect properties of light. This topic is significant because it could overcome current cost/performance issues of tandem detectors, enabling widespread usage. The expected project outcome is the development of a novel tandem 2D detector, which as a single detector/pixel, can extract the intensity, polarisation and wavelength region of incoming light. This would provide benefits for many future applications, including machine vision and aerial surveying.Read moreRead less

This project will focus on a goal of engineering novel plasmonic metamaterials for manipulating light at the nanoscale. In particular, it will employ curved anodized alumina templates as well as 3D hybrid structures to explore light bending and strong resonances at the visible spectral range. Plasmonic metamaterials offer a unique ability to control subwavelength light propagation, for achieving unprecedented sensing sensitivities and emerging nanophotonics phenomena. However, fabrication challenges and high losses hamper their application in the visible spectral range. Engineering these plasmonic structures in a scalable manner should strengthen Australia’s economy, lead to new industrial companies in the emerging field of plasmonics, attract international investments and create job opportunities.Read moreRead less

The project seeks to develop high performance photoferroelectric materials for a wide range of photoenergy conversion technologies like photovoltaics and photocatalytics. For the past 50 years, ferroelectric photovoltaics have only been an academic curiosity due to their low energy conversion efficiency relative to the popular semiconductor photovoltaics. This project aims to unlock the potential of ferroelectric photovoltaics by introducing an ion co-substitution, which is coupled with electron-pinning, into promising ferroelectric materials and investigating the resultant photo-excited electronic and electrical properties. It is anticipated that the outcomes from this proposed project will provide a solution for optimal ferroelectric visible light absorption to achieve high power conversion efficiency in ferroelectric materials for practical photoenergy applications.Read moreRead less
