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有半定量的理解。 重点是氧化物和氧气材料。动机是利用这些知识来设计新材料或重新发现现有材料，具有有趣的光学，电气和/或催化特性。特定的重点是新材料的发展，其中电气和光学性质都很重要，例如光催化剂和透明导体。可以有效利用可见光的光催化材料的开发在环境修复和产生氢的领域具有很大的影响。教育计划有两个方面。 第一个要素涉及改善通过将积极学习和小组工作的更多方面纳入朗诵和实验室部分来教授通用化学的方式。教育计划的第二个方面是开发一系列模块，用于在研究生/高级本科层面教授固态化学方面。选择此处描述的研究和教育组成部分是为了增强我们对固态化学中结构组合特性关系的理解。对新透明导体的需求是由光电设备的日益普及（例如平面面板显示器）的日益普及的驱动的。二极管和太阳能电池。在该领域接受培训的学生有很大的机会在这些高科技工作市场中竞争。
