项目摘要

AbstractCHE-0317114Pemberton/ArizonaWith the support of the Analytical and Surface Chemistry Program, Professor Pemberton and her colleagues at the University of Arizona are carrying out a broad based examination of interfaces in electrochemical devices, including solid-state molecular photonics and electronic devices. Surface vibrational spectroscopies in combination with work function measurement, electron spectroscopy, and temperature programmed desorption methods are used to examine the interfaces between low work function metals and organic polymers and small molecules. Interfaces in organic heterojunctions are also being examined. Studies of emersion are also being carried out, in order to understand the processes of surface wetting and electrowetting in electrochemical devices. Information obtained from these studies is useful in the design of electronic materials processing protocols and for the design of photonic and electronic devices. Professor Pemberton and her coworkers at the University of Arizona have developed an effective combination of spectroscopic and electrochemical tools to examine the structure and properties of interfaces in electrochemical and electronic devices. Interfaces between reactive metals and organic layers, between organic layers of different composition, and at the emersed metal-electrolyte junction are being examined. The results of these studies are useful for the design and processing of microelectronic materials and systems.

Pemberton/Arizona在分析和表面化学项目的支持下，亚利桑那大学的Pemberton教授和她的同事们正在对电化学器件中的界面进行广泛的研究，包括固态分子光子学和电子器件。表面振动光谱结合功函数测量，电子能谱和温度程序解吸方法用于检查低功功能金属与有机聚合物和小分子之间的界面。有机异质结中的界面也在研究中。为了了解电化学装置中的表面润湿和电润湿过程，也正在进行再现研究。从这些研究中获得的信息对电子材料加工方案的设计以及光子和电子器件的设计是有用的。彭伯顿教授和她在亚利桑那大学的同事们开发了一种有效的光谱和电化学工具的组合，用于检查电化学和电子设备中界面的结构和性质。研究了活性金属与有机层之间的界面，不同组成的有机层之间的界面，以及出现的金属-电解质连接处的界面。这些研究结果对微电子材料和系统的设计和加工具有指导意义。
