Electrode Surface Structure

在这项由分析和表面化学计划支持的研究项目中，辛辛那提大学的Arthur Hubbard教授和他的学生将测量各种具有原子和分子覆盖的、具有良好特征的表面发射的俄歇电子的详细角分布。这些角分布将与基于电子发射过程竞争模型预测的分布进行仔细的比较，以便开发一种从角分布中提取表面结构信息的方法。电极表面覆盖层的表面结构信息将使我们能够详细了解这些界面上发生的电化学。电化学在从传感器到电池的大量技术应用中都是重要的。为了了解在这些广泛的电化学应用中发生在电极表面的化学，必须知道电极的结构以及与其相关的任何原子或分子覆盖层。这项研究项目旨在开发一种基于测量从这些表面发射的电子的角分布的方法来分析这些覆盖层的结构。

In this research project, supported by the Analytical and Surface Chemistry Program, Professor Arthur Hubbard and his students at the University of Cincinnati will measure the detailed angular distributions of emitted Auger electrons for a variety of well characterized surfaces with atomic and molecular overlayers. These angular distributions will be carefully compared with the distributions predicted based on competing models of the electron emission process, in order to develop a method for extracting surface structural information from the angular distributions. Surface structural information for overlayers on electrode surfaces will enable a detailed understanding of the electrochemistry occurring at these interdaces. Electrochemistry is important in an enormous number of technological applications, ranging from sensors to batteries. In order to understand the chemistry which occurs at the electrode surface in these wide ranging electrochemical applications, one must know the structure of the electrode and any atomic or molecular overlayers associated with it. This research project is designed to develop a method for structural analysis of these overlayers based on the measurement of the angular distribution of electrons emitted from these surfaces.
