该研究项目在马里兰大学帕克分校的Janice Bett-Robey教授的实验室中进行，研究了在表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。 在分析和表面化学计划的支持下，正在使用扫描隧道显微镜检查Al（111）表面上形成的铝烷低聚物的详细结构和运动。 一个类似的方法是用来检查的结构和反应性的有序架构形成的吸附N-杂芳族羧酸的银表面。 从这些研究中获得的信息是我们理解纳米尺度电子器件的生长和操作的基础。利用扫描隧道显微镜和其他表面敏感工具，马里兰州大学的Robett-Robey教授和她的同事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尺度器件的形成有关。 原子氢与铝表面的相互作用，形成有序的低聚物的表面上正在检查。 此外，吸附和相互作用的强氢键含氮芳香酸正在审查。 从这些研究中获得的信息将为表面纳米尺度结构的合成和操作提供重要的基础。

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.
