Professor Paul Weiss and his coworkers in the Department of Chemistry at the Pennsylvania State University are using a number of scanning probe microscopic methods to examine various aspects of single molecule electronics. With the support of the Analytical and Surface Chemistry Program, Weiss and coworkers are addressing questions of molecule orientation, photoactivation, molecular conductivity, and molecular switching in self-assembled monolayer model systems. Measurements are made with scanning probe methods developed in the Weiss laboratory. Fundamental information from these studies is useful for developing design considerations and materials choices for molecular electronic devices. In order to realize the promise of molecular electronic devices, fundamental information about molecule conductivity, switching behavior, photoactivation, and stability is needed. Professor Weiss and his coworkers in the Department of Chemistry at the Pennsylvania State University are using scanning probe microscopy studies of molecules embedded in self-assembled monolayer model systems to obtain this sort of information. Material and interfacial properties of these model systems are determined, providing fundamental information for device design.

宾夕法尼亚州立大学化学系的保罗·韦斯教授和他的同事们正在使用一些扫描探针显微镜方法来研究单分子电子学的各个方面。在分析和表面化学计划的支持下，Weiss和他的同事正在研究自组装单层模型系统中的分子取向、光激活、分子导电性和分子开关等问题。测量是用Weiss实验室开发的扫描探头方法进行的。这些研究的基本信息对发展分子电子器件的设计考虑和材料选择是有用的。为了实现分子电子器件的前景，需要关于分子导电性、开关行为、光激活和稳定性的基本信息。韦斯教授和他在宾夕法尼亚州立大学化学系的同事正在使用扫描探针显微镜对嵌入到自组装单层模型系统中的分子进行研究，以获得此类信息。确定了这些模型体系的材料和界面性质，为器件设计提供了基础信息。
