National facility for nanoscale characterisation of luminescent materials. The project aims to establish a national facility for nanoscale characterisation of advanced optoelectronic materials, including atomically-thin materials, luminescent nanocrystals, metamaterials, and plasmonic nanostructures.

The project aims to establish a national facility for nanoscale characterisation of advanced optoelectronic materials, including atomically-thin materials, luminescent nanocrystals, metamaterials, and plasmonic nanostructures. The combination of a highly focused electron beam, and novel light detection optics, will enable temperature-dependent, angle, polarisation and time-resolved luminescence analysis with unprecedented resolution. It is expected this will yield discoveries in nanoscale physics and materials science. It will create interdisciplinary collaborations by linking Australian scientists who use high-resolution multimodal characterisation methods to innovate and develop materials and device technologies.Read moreRead less
New insights into fundamental carrier transport in type-II superlattices. Type-II superlattice (T2SL) based semiconductors have emerged as a rival to well-established HgCdTe-based IR detectors, promising comparable performance at significantly lower cost. T2SLs are complex nanostructures that exhibit multiple-carrier and highly-anisotropic electronic transport properties, which renders them exceedingly challenging to study experimentally. The lack of reliable experimental data has limited optimi ....New insights into fundamental carrier transport in type-II superlattices. Type-II superlattice (T2SL) based semiconductors have emerged as a rival to well-established HgCdTe-based IR detectors, promising comparable performance at significantly lower cost. T2SLs are complex nanostructures that exhibit multiple-carrier and highly-anisotropic electronic transport properties, which renders them exceedingly challenging to study experimentally. The lack of reliable experimental data has limited optimisation and modelling efforts, and thus hampered progress. This project aims to systematically study electronic transport in T2SLs, both experimentally and theoretically, by employing world-leading mobility spectrum techniques developed at UWA and state-of-the art T2SL structures from three world leaders in T2SLs.Read moreRead less

Passivating Cadmium free Cu2ZnSn(S,Se)4 solar cell by contact engineering. The project aims to develop new solar cells made of low cost abundant elements. The cells are cadmium-free copper zinc tin sulphide (CZTS) cells formed by rear contact passivation and damage-free evaporated front layers. CZTS has the same efficiency potential as current commercial copper indium gallium selenide (CIGS) cells, but consists of low cost, abundant elements.

The project aims to develop new solar cells made of low cost abundant elements. The cells are cadmium-free copper zinc tin sulphide (CZTS) cells formed by rear contact passivation and damage-free evaporated front layers. CZTS has the same efficiency potential as current commercial copper indium gallium selenide (CIGS) cells, but consists of low cost, abundant elements. Concepts and methods will be developed for passivation of CZTS solar cells via both back and front contact engineering. The cadmium- free buffer layer will be investigated and the application of CZTS will be expanded. This work may be applied to CIGS improvement and could give CZTS materials a significant role in the rapidly growing photovoltaic industry.Read moreRead less
