Exploratory synthesis and characterisation of novel metal subchalcogenides and metal oxo-chalcogenides

在Kanatzidis教授的国际领先团队中，为有前景的材料学习新的合成技术和表征方法是这项提议的意义所在。该项目将研究新型金属亚硫化物和金属氧硫化物的探索性合成和表征。我们将采取包括化学家、物理学家和电气工程师在内的多学科方法，合成具有优化性能的热电材料。当这些材料与放热过程相结合时，可能会导致更有效地利用能源。采用不同的助熔剂可以合成金属氧硫族化合物。这一部分的重点是发展通用的综合方法。适当设计的助熔剂有望产生具有离子交换或非线性光学二次谐波等有趣性质的半导体金属氧硫化物材料。

Learning new synthetic techniques and characterisation methods for promising materials in the internationally leading group of Professor Kanatzidis is what this proposal is about. The project will investigate the exploratory synthesis and characterisation of novel metal subchalcogenides and metal oxo-chalcogenides. Taking a multidisciplinary approach involving chemists, physicists and electrical engineers, we will synthesise thermoelectric materials with optimised properties. These materials could lead to a more efficient use of energy when coupled to exothermic processes. Metal oxo-chalcogenides will be synthesised by applying different fluxes. The emphasis of this part is on developing generalized synthesis methodologies. Suitably designed fluxes are expected to give rise to semiconducting metal oxo-chalcogenide materials with interesting properties such as ionexchange or non-linear optical second harmonic generation.
