Chemical Control of Recombination at Semiconductor Interfaces

这个项目属于分析化学和表面化学的一般领域，属于异质光过程的子领域。在这项为期三年的持续资助中，Lewis教授和他的学生将研究半导体/液体界面的结构和电子特性。利用定义明确的半导体/液体接触，本研究试图深入了解控制(a)界面半导体域中的电场，(b)电荷从半导体相移动到接触相的速率，(c)半导体/接触相表面化学。半导体/液体接触在许多技术中都很重要，包括太阳能转换、有毒废物的光化学修复、化学传感器和分子电子器件。本研究目标的成功实现将导致上述及相关技术中半导体系统的更有效和更广泛的应用。

This project is in the general area of analytical and surface chemistry and in the subfield of heterogeneous photoprocesses. During the tenure of this three-year continuing grant, Professor Lewis and his students will investigate structural and electronic properties of semiconductor/liquid interfaces. Using well-defined semiconductor/liquid contacts, this research seeks insight into those factors which control (a) electric fields in the semiconductor domain of the interface, (b) the rate at which charges move from the semiconductor phase into the contacting phase, and (c) the semiconductor/contacting phase surface chemistry. %%% Semiconductor/liquid contacts are important in many technologies including solar energy conversion, photochemical remediation of toxic wastes, chemical sensors, and molecular electronic devices. The successful attainment of the goals of this research should result in the more efficient and widespread use of semiconductor systems in the aforementioned and related technologies.
