小行星9709351 该项目旨在合成、表征和研究固态金属硫属化物的物理性质,硫属化物是一类含有硫、硒或碲的材料。 研究的领域包括:(a)第四族金属的三元和四元硫属化物;(B)四元稀土硫属化物;(c)这些材料表现出的结构畸变和相应的能带结构计算;(d)稀土的硫属化物。 新材料的表征将包括通过单晶X射线方法确定结构和测量传输特性,特别是电导率和磁化率。 由于认为硫属化物可以提供丰富的新材料来源,因此重要的是扩展这些化合物的合成,作为具有可预测的化学、结构和性质/结构关系的技术相关新材料的可能来源。 最终目标是通过研究和教育的整合,使学生成为未来的科学家和工程师,能够提供具有半导体,绝缘体或磁性的新型固态材料。 ***
英文摘要
9709351 Ibers This project aims at the synthesis, characterization, and study of physical properties of solid-state metal chalcogenides, which are a class of materials that contain sulfur, selenium or tellurium. Among areas to be investigated are (a) ternary and quaternary chalcogenides of the Group IV metals; (b) quaternary rare-earth chalcogenides; (c) structural distortions exhibited by these materials, and the corresponding band-structure calculations; (d) chalcogenides of rhenium. Characterization of the new materials will include structure determinations by single- crystal X-ray methods and the measurement of transport properties, especially electrical conductivity and magnetic susceptibility. %%% Since it is felt that the chalcogenides may provide a rich source of novel materials, it is important to expand the synthesis of these compounds as a possible source of technologically relevant new materials with predictable chemistry, structure and property/structure relationships. The ultimate goal is to provide through the integration of research and education students as future scientists and engineers able to provide novel classes of solid-state materials that exhibit semiconductor, insulator, or magnetic properties. ***
