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

在Kanatzidis教授的国际领导小组中学习新的合成技术和有前途的材料的表征方法是这个提议的内容。该项目将探索新型金属亚硫族化合物和金属氧硫族化合物的探索性合成和表征。采用涉及化学家，物理学家和电气工程师的多学科方法，我们将合成具有优化性能的热电材料。当与放热过程相结合时，这些材料可以更有效地利用能源。应用不同的助熔剂可合成金属氧硫族化合物。这一部分的重点是发展一般的综合方法。适当设计的通量有望产生具有有趣性质的半导体金属氧硫族材料，如离子交换或非线性光学二次谐波产生。

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.
