This CAREER proposal, supported in the Analytical and Surface Chemistry Program, addresses questions of the reactivity of organic thin films with "open shell" atomic and radical reactants. Professor Kandel and his coworkers at the University of Notre Dame, are examining the reactions of functionalized self assembled thiol monolayers with atomic reactants such as hydrogen and oxygen. Reactivity is probed by examining the reacted surface with Auger electron spectroscopy, thermal desorption spectroscopy, and scanning tunneling microscopy. As part of this research project, Kandel will develop an undergraduate course that focusses on the construction of a simple scanning tunneling microscope, demonstrating the process of instrument design while illustrating important concepts in solid state and surface science. The results of this research activity provide fundamental understanding of gas-surface reaction processes important in electronic materials processing, in plasmas, flames, and upper atmosphere chemistry. With the support of the Analytical and Surface Chemistry Program, Professor Kandel and his coworkers at Notre Dame are investigating the interaction of reactive atomic and radical species with model organic thin films. The results of these studies provide fundamental information about the gas-surface reaction chemistry of organic surfaces important in lubrication, electronic devices, polymer surfaces, and combustion environments. The educational aspect of this CAREER award includes the development of a course focussing on instrument design.

这项职业计划得到了分析和表面化学计划的支持，解决了有机薄膜与“开壳”原子和自由基反应物的反应性问题。圣母大学的坎德尔教授和他的同事正在研究功能化的自组装硫醇单分子膜与氢和氧等原子反应物的反应。用俄歇电子能谱、热脱附谱和扫描隧道显微镜对反应表面进行了表征。作为这一研究项目的一部分，坎德尔将开发一门本科课程，专注于构建简单的扫描隧道显微镜，演示仪器设计过程，同时说明固体和表面科学中的重要概念。这项研究活动的结果提供了对电子材料加工、等离子体、火焰和高层大气化学中重要的气体-表面反应过程的基本了解。在分析和表面化学计划的支持下，圣母大学的坎德尔教授和他的同事们正在研究反应原子和自由基物种与模型有机薄膜的相互作用。这些研究结果提供了在润滑、电子器件、聚合物表面和燃烧环境中重要的有机表面的气体-表面反应化学反应的基本信息。这一职业奖项的教育方面包括开发一门专注于仪器设计的课程。
