Synthesis and Characterization of New Transition Metal Pnictides and Pnictide Oxides and Their Characterization

本课题主要研究了新型三元过渡金属pnictide及其氧化物相的合成。它将探索性综合与系统的结构性质研究相结合。主要的重点是性质测量和化合物的特征，包括碱土或稀土与过渡金属和15族镍元素，以及这些混合物的亚氧化物。这个小组利用Zintl的概念来指导新的磁性和电子化合物的合成。这种方法为发现新的结构和性质提供了一个良好的起点。为了探索新的化合物和测量性质，通量将用于生产大晶体。此外，还将研究这些镍酸盐和层状镍酸盐氧化物的新性质和结构-性能关系。主要目标是培养学生在固态合成和表征技术。学生参与新发现和财产测量的各个方面。提案中概述的一些实验利用了国家设施，如先进光源和劳伦斯伯克利实验室的国家电子显微镜中心。此外，与劳伦斯利弗莫尔国家实验室的化学、物理和材料科学小组也有强有力的合作。这种类型的协同作用为学生提供了全面的教育，并为当今工业的多学科科学做好准备。此外，对本科生的教育和向公众宣传材料合成对我们未来技术进步的重要性也是该项目的一个主题。新材料的开发是新技术的重要基石。这一发展的基本问题之一是新材料的合成与性能测量相结合。将合成与最先进的表征工具相结合，旨在发现新的磁性和电子材料，大大提高了及时技术影响的机会。

This project focuses on the synthesis of new ternary transition metal pnictide and pnictide oxide phases. It combines exploratory synthesis with systematic structure-property studies. The primary emphasis is on property measurements and characterization of compounds involving alkaline earth or rare earth with transition metals and the group 15 pnictide elements, along with the suboxides of these mixtures. This group utilizes the Zintl concept to direct the synthesis of new magnetic and electronic compounds. The approach provides a good starting place for the discovery of new structures and properties. In order to explore new compounds and to measure properties, fluxes will be used to produce large crystals. In addition novel properties and structure-property relationship of these pnictide and layered pnictide-oxides will be investigated. The primary goal is to train students in solid state synthesis and characterization techniques. Students are involved in all aspects of new discovery and property measurements. Some of the experiments outlined in the proposal make use of national facilities such as the Advance Light Source and the National Center for Electron Microscopy at Lawrence Berkeley Laboratory. In addition, there is a strong collaboration with chemistry, physics, and materials science groups at Lawrence Livermore National Laboratory. This type of synergism provides the student with a well-rounded education and prepares them for the multidisciplinary science of today's industry. In addition, the education of undergraduates and outreach to the general public in the importance of materials synthesis to our future technological advances is included as a theme of the project. The development of new materials is an important cornerstone of new technologies. One of the fundamental issues in this development is the synthesis of new materials coupled with property measurements. Combining synthesis with state-of-the-art characterization tools with an aim towards discovering new magnetic, and electronic materials significantly enhances the chances of timely technological impacts.
