AbstractCHE-0404587Yarmoff/UC-RiversideProfessor Yarmoff and his colleagues at the University of California-Riverside are studying the fundamental aspects of the interactions of ions with solid surfaces. Using metal and semiconductor probe ions, they are investigating the charge resolved scattering of low energy ions from metal and semiconductor surfaces. They are using these probes to evaluate the unique electronic states of nano-scaled materials. Collaboration with Professor Sroubek of the Czech Republic addresses the fundamental theory of these charge exchange and charge neutralization processes. The Analytical and Surface Chemistry Program provides these researchers with support to examine these fundamental processes. The impact of this work on related areas of surface analysis, surface modification, electronic device processing and catalysis is likely to be significant. With the support of the Analytical and Surface Chemistry Program, Professor Yarmoff and his collaborators at UC-Riverside are probing the fundamentals of ion-solid interactions. A range of substrates are being examined, including nano-clusters of metals and semiconductors. Fundamental understanding of the ion-surface interaction is crucial to important applications in electronic device processing, heterogeneous catalysis, and nanomaterial synthesis and processing.

Yarmoff/UC-RiversideYarmoff教授和他在加州大学河滨分校的同事们正在研究离子与固体表面相互作用的基本方面。 利用金属和半导体探针离子，他们正在研究低能离子从金属和半导体表面的电荷分辨散射。 他们正在使用这些探针来评估纳米尺度材料的独特电子状态。 与捷克共和国的Sroubek教授的合作解决了这些电荷交换和电荷中和过程的基本理论。 分析和表面化学计划为这些研究人员提供支持，以检查这些基本过程。 这项工作对表面分析、表面改性、电子器件加工和催化等相关领域的影响可能是重大的。在分析和表面化学计划的支持下，Yarmoff教授和他在加州大学河滨分校的合作者正在探索离子-固体相互作用的基本原理。 一系列的基板正在研究中，包括金属和半导体的纳米簇。 对离子-表面相互作用的基本理解对于电子器件加工、多相催化和纳米材料合成和加工中的重要应用至关重要。
