Electrochemistry and Photoprocesses at Semiconductors

该研究项目由分析和表面化学计划支持，重点是进一步研究半导体/液体界面和有机光电导体/液体界面。 德克萨斯大学奥斯汀分校的巴德教授和他的学生将扩大他们的研究，包括新的III-V族氮化物半导体材料。 在这个项目中，原子力显微镜和扫描电化学显微镜将用于电化学测量。 由于在这些界面处发生的光电化学过程的效率提高了可能的水分解反应，因此将追求光催化废物处理过程和新的存储器件的开发，需要更有效地将太阳能的转换与在固/液界面处驱动的电子转移反应耦合。 德克萨斯大学奥斯汀分校的巴德教授和他的学生开创了半导体/液体和有机光电导体/液体界面的研究。 在这项工作中，将研究一系列新的半导体材料，目的是提高这些光电化学反应的效率。 这项工作的实际进展包括改进水的分解和更有效的光电化学废物处理过程。 在这项工作中还将开发新的存储设备。

This research project supported by the Analytical and Surface Chemistry Program, focuses on the further study of semiconductor/liquid interfaces and organic photoconductor/liquid interfaces. Professor Bard and his students at the University of Texas at Austin will extend their studies to include new group III-V nitride semiconductor materials. In this project atomic force microscopy and scanning electrochemical microscopy will be used with electrochemical measurements. As the efficiency of photoelectrochemical processes occurring at these interfaces improves possible water splitting reactions, photocatalytic waste treatment processes, and the development of new memory devices will be pursued.There is a need to more efficiently couple the conversion of solar energy with electron transfer reactions driven at solid/liquid interfaces. Professor Bard and his students at the University of Texas at Austin have pioneered studies of semiconductor/liquid and organic photoconductor/liquid interfaces for these purposes. A family of new semiconductor materials will be studied in this work with the aim to improve the efficiency of these photoelectro-chemical reactions. Among the practical advances envisaged for this work is improved splitting of water and more efficient photoelectrochemical waste treatment processes. New memory devices will also be developed in this work.
