Order-disorder control in functional oxides

概述：许多功能材料的可利用性质（例如其电子、磁性或介电性质）与其原子结构密切相关。这个项目将研究各种金属氧化物系统，其中原子有序-无序转变的控制可以用来调节性能。该项目将涉及合成已知的和新的多晶和单晶样品，并测量其物理特性（导电性、磁性、热容等）。结构与性能的相关性将使用布拉格晶体学（粉末和单晶），总散射或PDF测量（多晶样品）和单晶漫散射研究的组合进行探测。

Overview: The exploitable properties of many functional materials (e.g. their electronic, magnetic or dielectric properties) are intimately linked to their atomic structure. This project will investigate a variety of metal oxide systems where control of atomic order-disorder transitions can be used to tune properties. The project will involve the synthesis of both known and novel polycrystalline and single-crystal samples, and the measurement of their physical properties (conductivity, magnetism, heat capacity, etc). The correlation of structure with properties will be probed using a combination of Bragg crystallography (powders and single crystals), total scattering or PDF measurements (polycrystalline samples) and single crystal diffuse scattering studies.
