Professor Allen Bard of the University of Texas Austin is supported by the Analytical and Surface Chemistry Program to study photoelectrochemical and optoelectronic effects in solid thin films and nanoparticle dispersions. The materials include traditional semiconductors like silicon and CdSe (quantum dots), as well as molecular films of substituted porphyrins, conjugated organics and inorganic salts. Low melting liquid crystals will be investigated, as well as inorganic molecular crystals like tris (2,2'-bipyridine)ruthenium(II). Methods include electrochemistry and electrogenerated chemiluminescence as well as scanning probe microscopy. Charge transfer and electrical characteristics of novel material films are not well understood, and fundamental studies could lead to better high density memories, light emitting diodes and other electronic devices. Nontraditional semiconductor materials will be explored, with potential use in solar energy conversion and charge storage devices, for example.

德克萨斯大学奥斯汀分校的艾伦巴德教授得到了分析和表面化学项目的支持，研究固体薄膜和纳米颗粒分散体中的光电化学和光电效应。 这些材料包括硅和CdSe（量子点）等传统半导体，以及取代卟啉、共轭有机物和无机盐的分子膜。 将研究低熔点液晶，以及无机分子晶体，如三（2，2 '-联吡啶）钌（II）。 方法包括电化学和电致化学发光以及扫描探针显微镜。 新材料薄膜的电荷转移和电学特性还没有得到很好的理解，基础研究可能会导致更好的高密度存储器，发光二极管和其他电子器件。 将探索非传统半导体材料，例如在太阳能转换和电荷存储设备中的潜在用途。
