This project aims to develop a semi-quantitative understanding of the relationships between composition, crystal structure and the electronic structure in extended solids. The focus is on oxide and oxynitride materials. The motivation is to use this knowledge to design new materials, or rediscover existing materials, with interesting optical, electrical and/or catalytic properties. Specific emphasis is given to the development of new materials where both the electrical and optical properties are important, such as photocatalysts and transparent conductors. The development of a photocatalytic material that can efficiently utilize visible light would have far reaching implications in the areas of environmental remediation and hydrogen generation. There are two aspects to the educational plan. The first element involves improving the way general chemistry is taught by incorporating more aspects of active learning and group work into the recitation and laboratory sections. The second aspect of the educational plan is to develop a series of modules for use in teaching solid state chemistry at the graduate/advanced undergraduate level. The combined research and education components described here were chosen to enhance our understanding of structure-composition-property relations in solid state chemistry.The need for new transparent conductors is driven by the increasing popularity of optoelectronic devices, such as flat panel displays, light emitting diodes, and solar cells. Students trained in the areas have a significant chance of competing well in these high-technology job markets.

这个项目的目的是对扩展固体中的组成、晶体结构和电子结构之间的关系进行半定量的了解。重点放在氧化物和氮氧化物材料上。其动机是利用这些知识来设计新材料，或重新发现具有有趣的光学、电学和/或催化性能的现有材料。特别强调了新材料的发展，其中电学和光学性能都很重要，如光催化剂和透明导体。开发一种能够有效利用可见光的光催化材料将在环境修复和制氢领域产生深远的影响。教育计划有两个方面。第一个要素涉及改进普通化学的教学方法，在复习和实验室部分融入更多主动学习和小组作业的方面。教育计划的第二个方面是开发一系列模块，用于在研究生/高级本科生水平上教授固态化学。这里描述的研究和教育相结合的组成部分是为了加深我们对固态化学中结构-组成-性质关系的理解。由于平板显示器、发光二极管和太阳能电池等光电子器件的日益普及，对新的透明导体的需求不断增加。在这些领域接受过培训的学生有很大的机会在这些高科技的就业市场上竞争。
