Formation and Structure-Property Relationships of Molecular Surface Architectures

这个研究项目是在马里兰大学帕克分校Janice reut - robey教授的实验室里进行的，研究了在特征良好的金属表面上形成的分子尺度结构的结构和反应性。在分析和表面化学程序的支持下，使用扫描隧道显微镜对Al（111）表面形成的烷烃低聚物的详细结构和运动进行了研究。一个类似的方法被用来检查由n -杂芳香羧酸在银表面吸附形成的有序结构的结构和反应性。从这些研究中获得的信息对于我们理解纳米级电子器件的生长和运行是至关重要的。利用扫描隧道显微镜和其他表面敏感工具，罗伊特-罗比教授和她在马里兰大学的同事们正在探索一系列有趣的化学系统的吸附和反应，这些化学系统与纳米级设备的形成有关。研究了原子氢与铝表面形成有序低聚物的相互作用。同时，对含强氢键氮的芳香酸的吸附和相互作用进行了研究。从这些研究中获得的信息将为在表面上合成和操纵纳米级结构提供重要的基础。

This research project, in the laboratory of Professor Janice Reutt-Robey at the University of Maryland-College Park, investigates the structure and reactivity of molecular scale architectures formed on well characterized metal surfaces. With the support of the Analytical and Surface Chemistry Program, the detailed structure and motion of alane oligomers formed on the Al(111) surface are being examined using scanning tunneling microscopy. A similar approach is used to examine the structure and reactivity of ordered architectures formed by the adsorption of N-heteroaromatic carboxylic acids on the silver surface. Information obtained from these studies is fundamental to our understanding of the growth and operation of nano-scale electronic devices.Using scanning tunneling microscopy and other surface sensitive tools, Professor Reutt-Robey and her coworkers at the University of Maryland are probing the adsorption and reaction of a range of interesting chemical systems with connections to the formation of nano-scale devices. The interaction of atomic hydrogen with aluminum surfaces to form ordered oligomers on the surface is being examined. Also, the adsorption and interaction of strongly hydrogen bonding nitrogen containing aromatic acids is being examined. The information gained from these studies will provide important underpinning for the synthesis and manipulation of nano-scale architectures on surfaces.
