AbstractCHE-0241425Hanley/Illinois-ChicagoThis research project, supported in the Analytical and Surface Chemistry Program, focuses on the use of hyperthermal polyatomic ions to form specific organic thin films. Using mass-selected and non-mass selected ion sources, the growth of thiophenic thin films is examined. The effects of ion energy, ion fluence, ion-neutral ratio in the source beam, and ion structure are correlated with properties of the grown thin film. Fundamental information about how organic films can be grown from characterized ion sources is useful for the development of organic electronic devices, flexible solar energy cells, and the understanding of related plasma processing methods. Professor Hanley and his colleagues at the University of Illinois-Chicago have developed a unique capability to carry out these studies. With the support of the Analytical and Surface Chemistry Program, Professor Hanley and his coworkers at the University of Illinois-Chicago are examining the growth of organic films using polyatomic ion sources. Unique polythiophenic films that may have application in flexible solar cell devices have been constructed, and the fundamental understanding of the growth of these films is being pursued. Ion beam characteristics are compared with the morphology and properties of the grown films in this work.

AbstractCHE-0241425Hanley/Illinois-ChicagoThis研究项目得到了分析和表面化学计划的支持，重点是利用高温多原子离子形成特定的有机薄膜。采用质量选择和非质量选择两种离子源，研究了噻吩类薄膜的生长过程。离子能量、离子注量、源束中性率和离子结构对薄膜性能的影响是相关的。有关如何从特征化的离子源生长有机薄膜的基本信息对于开发有机电子器件、柔性太阳能电池以及了解相关的等离子体处理方法都是有用的。伊利诺伊大学芝加哥分校的汉利教授和他的同事们已经开发出一种进行这些研究的独特能力。在分析和表面化学计划的支持下，伊利诺伊大学芝加哥分校的汉利教授和他的同事们正在研究使用多原子离子源生长有机薄膜。可以应用于柔性太阳能电池器件的独特的聚噻吩膜已经被构建，并正在寻求对这些膜的生长的基本了解。在这项工作中，离子束特性与生长的薄膜的形貌和性能进行了比较。
