This project aims to investigate the correlation between structural and electronic drivers of behaviour in complex metal oxides. Transition metal oxides are critical for modern electronics and discovering new materials and determining their physical properties is essential for the introduction of new technologies. This project will synthesis and characterise thermally novel oxides containing 4d and 5d transition metals to establish the relationships between the chemistry, crystal structure and physical properties of such oxides. The unusual hierarchy of interactions in such oxides, and high sensitivity to crystal fields and subtle structural distortions, makes such oxides candidate materials for the realisation of various emergent quantum phases that may be used in the next generation of electronics. The proposal has the potential to significantly advance Australian research and development capacity in advanced materials and the associated high-tech industries.

该项目旨在研究复杂金属氧化物行为的结构和电子驱动因素之间的相关性。过渡金属氧化物对现代电子学至关重要，发现新材料并确定其物理性质对于引入新技术至关重要。本项目将合成和热分解含有4d和5d过渡金属的新型氧化物，以建立此类氧化物的化学，晶体结构和物理性质之间的关系。这种氧化物中不寻常的相互作用层次，以及对晶体场和微妙结构扭曲的高敏感性，使得这种氧化物成为实现各种涌现量子相的候选材料，这些量子相可能用于下一代电子学。该提案有可能大大提高澳大利亚在先进材料和相关高科技产业方面的研发能力。
