这个CAREER提案，在分析和表面化学计划的支持下，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。坎德尔教授和他在圣母大学的同事们正在研究功能化的自组装硫醇单层与原子反应物（如氢和氧）的反应。通过使用俄歇电子能谱、热解吸能谱和扫描隧道显微镜检查反应表面来探测反应性。作为该研究项目的一部分，坎德尔将开设一门本科课程，重点是构建一个简单的扫描隧道显微镜，展示仪器设计的过程，同时说明固态和表面科学的重要概念。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理解。在分析和表面化学项目的支持下，坎德尔教授和他在圣母大学的同事们正在研究反应性原子和自由基与模型有机薄膜的相互作用。这些研究结果为润滑、电子设备、聚合物表面和燃烧环境中重要的有机表面的气表面反应化学提供了基本信息。该职业奖的教育方面包括开发一门以乐器设计为重点的课程。

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.
