Rabalais/Houston休斯顿大学的Rabalais教授和他的同事，以及他的理论同事拉马尔大学的Bahrim教授沿着，正在开发离子-电子符合光谱学，以探测固体表面的化学结构。 在分析和表面化学计划的支持下，他们将离子-电子重合的详细实验研究与轨迹计算相结合，以发展对离子-固体相互作用的基本理解。 这项工作的目标是开发固体表面的真实的空间结构和化学分析工具。 这些信息的应用在许多重要技术中至关重要，包括半导体加工，多相催化和等离子体壁相互作用。 使用实验和理论方法相结合，教授Rabalais和Bahrim正在开发固体表面的结构和成分分析方法。 离子-电子符合光谱提供了固体表面的电荷转移映射，并可用于了解界面处的化学反应性。 这些研究的基本信息在微电子器件和固体催化剂的分析中是重要的。

AbstractCHE-0303708Rabalais/HoustonProfessor Rabalais and his coworkers at the University of Houston, along with his theoretical colleague Professor Bahrim at Lamar University, are developing ion-electron coincidence spectroscopy to probe the chemical structure of solid surfaces. With the support of the Analytical and Surface Chemistry Program, they are combining detailed experimental studies of ion-electron coincidence with trajectory calculations to develop a fundamental understanding of ion-solid interactions. The goal of this work is to develop tools for the real space structural and chemical analysis of solid surfaces. Application of this information is critical in a number of important technologies, including semiconductor processing, heterogeneous catalysis, and plasma-wall interactions. Using a combination of experimental and theoretical approaches, Professors Rabalais and Bahrim are developing methods for the structural and compositional analysis of solid surfaces. Ion-electron coincidence spectroscopy provides a charge transfer mapping of the solid surface, and can be used to understand chemical reactivity at the interface. Fundamental information from these studies is important in the analysis of microelectronic devices and solid catalysts.
