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.

该项目旨在半定量地理解扩展固体中的成分、晶体结构和电子结构之间的关系。 重点是氧化物和氮氧化物材料。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/或催化特性的现有材料。特别强调电学和光学性能都很重要的新材料的开发，例如光催化剂和透明导体。开发能够有效利用可见光的光催化材料将对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。 第一个要素涉及通过将主动学习和小组工作的更多方面纳入背诵和实验部分来改进普通化学的教学方式。教育计划的第二个方面是开发一系列用于研究生/高年级本科生固体化学教学的模块。选择此处描述的综合研究和教育部分是为了增强我们对固态化学中结构-成分-性能关系的理解。光电器件（例如平板显示器、发光器件）的日益普及推动了对新型透明导体的需求二极管和太阳能电池。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就业市场上竞争。
