9901165科尔曼这一跨学科的项目旨在研究嵌入重金属碘化物，包括（1）新材料的合成和配方（2）在这些材料中的键合机制的调查，以优化其性能，（3）在研究项目中的代表性不足的本科生参与。 重点将放在研究这些宽带隙半导体的光敏性，光成像和键合机制。 插层的铅，镉，铋碘与小客体分子将产生一个新的类的插层化合物不同于石墨和过渡金属-二硫属化物系统。 确定控制键合的因素将为控制和优化这类新材料的独特光学特性提供见解。%观察到这些材料在带边以上的光学吸收的大幅增加和在带边以下的吸收的减少产生尖锐的光学带边，其可以被优化用于包括可见光太阳能电池、高分辨率光成像和高速光学开关的应用。 这一多学科建议得到多学科事务办公室的共同支持。

9901165ColemanThis interdisciplinary project aims to investigate intercalation in heavy metal iodides including (1) the synthesis and formulation of new materials (2) investigation of the bonding mechanisms in these materials to optimize their performance, and (3) involvement of under represented undergraduate students in research projects. The emphasis will be on studying the photosensitivity, photoimaging, and bonding mechanisms in these wide bandgap semiconductors. Intercalation of lead-, cadmium-, and bismuth-iodides with small guest molecules will generate a new class of intercalation compounds distinct from both the graphite and transition-metal-dichalcogenide systems. Determining the factors that control bonding will provide insights into controlling and optimizing the unique optical properties of this new class of materials.%%%A large increase in the optical absorption above the band-edge and a decrease in absorption below the band edge is observed for these materials produce sharp optical band edges that can be optimized for applications that include visible light solar cells, high resolution photoimaging, and high-speed optical switches. This multidisciplinary proposal is jointly supported by the Office of Multidisciplinary Affairs.
