The role of interstitial oxide and superoxide anions in ionic conductors. This project seeks to understand how defects and local disorder can facilitate solid-state ionic conductivity in complex oxides. Particular attention will be paid to the under-explored mechanisms by which excess oxygen can be incorporated in these oxides, as opposed to the conventional scenario in which conduction occurs through vacant sites due to an oxygen deficiency. The project aims to characterise the target oxides at ....The role of interstitial oxide and superoxide anions in ionic conductors. This project seeks to understand how defects and local disorder can facilitate solid-state ionic conductivity in complex oxides. Particular attention will be paid to the under-explored mechanisms by which excess oxygen can be incorporated in these oxides, as opposed to the conventional scenario in which conduction occurs through vacant sites due to an oxygen deficiency. The project aims to characterise the target oxides at various length scales using advanced diffraction, spectroscopy and imaging methods, to obtain a holistic multi-scale picture of their structures. It is expected that this will reveal the structure-property relationships required to rationally design new and improved oxide-ion conductors for applications such as solid oxide fuel cells.Read moreRead less
