Professor Sosolik and his coworkers in the Physics Department at Clemson University are examining the interactions of hyperthermal ions with chemicurrent-sensing Schottky diode devices. The goal of this work, supported by the Analytical and Surface Chemistry Program, is to understand energy and charge transfer processes in hyperthermal ion-surface interactions, and to examine the role of spin in ion neutralization processes. This fundamental understanding broadly impacts the development of sensor devices and spin dependent ion-surface interaction systems. A comprehensive educational plan focused on nanoscience integrates this research with educational outreach and involves a broad community of students and educators in this work. With the support of the Analytical and Surface Chemistry Program, Professor Sosolik is examining the detailed interaction of ions with thin layer Schottky diode sensor devices. The goal of this work is to develop an understanding of charge and energy transfer upon ion-surface collision, and to use this information as a foundation for the development of sensitive gas sensors. An educational outreach plan involving a broad range of constituencies is included in this CAREER development award.

克莱姆森大学物理系的Sosolik教授和他的同事正在研究超高温离子与化学电流传感肖特基二极管器件的相互作用。 这项工作的目标，由分析和表面化学计划的支持，是了解超高温离子表面相互作用中的能量和电荷转移过程，并检查自旋在离子中和过程中的作用。 这种基本的理解广泛地影响了传感器器件和自旋相关离子表面相互作用系统的发展。 一项以纳米科学为重点的全面教育计划将这项研究与教育推广相结合，并让广泛的学生和教育工作者社区参与这项工作。 在分析和表面化学计划的支持下，Sosolik教授正在研究离子与薄层肖特基二极管传感器器件的详细相互作用。 这项工作的目标是发展的离子表面碰撞后的电荷和能量转移的理解，并使用这些信息作为敏感的气体传感器的发展的基础。 这个职业发展奖包括一个涉及广泛选区的教育推广计划。
