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

Understanding the role of catalysts in the epitaxial growth of multinary III-V semiconductor nanowires and nanowire heterostructures. This project will address a bottle-neck problem in the nanowire community. The outcomes of this project will provide new knowledge in nanoscience and guidelines for the development of nanowire-based nanodevices and nanosystems. This is strategically important to place Australia at the forefront of developments on nanoscience and nanotechnology.

This project proposes a new broadband, high-power, laser technology for THz sensing. This semiconductor laser based THz technology is crucial for a wide range of applications requiring the acquisition of THz spectral signatures of materials and high-frame rate hyper-spectral THz imaging. We propose two pathways to engineer this novel THz technology: using a tuneable, coupled-cavity quantum cascade semiconductor laser and by creating the broad emission spectra through active mode locking in a THz semiconductor laser. The THz laser coupled with the self-detection technique is the key to realising this, and will be explored both in model and experiment.Read moreRead less
