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
