Spectroscopy of Single Molecules at Specific Sites on Surfaces

固体表面纳米尺寸特征和单个分子的化学鉴定是本研究项目的重点。在分析和表面化学项目的支持下，华盛顿州立大学的Hipps教授和他的同事们正在使用轨道介导隧道光谱结合扫描隧道显微镜来检查金属和石墨表面上大型有机和有机金属分子层的电子结构。研究了分子间填充和界面结构在决定这些层的电子输运性质中的作用。从这些研究中获得的信息将为基于分子的电子和光电子器件的设计提供基础信息。随着电子器件缩小到纳米级和分子级，需要更多关于这些分子电子器件的电子结构的基本信息。该研究项目由华盛顿州立大学Hipps教授的实验室进行，使用轨道介导的隧道光谱来获得金属和碳表面上表征良好的分子覆盖层的电子结构信息。除了这些研究获得的基本理解外，还将产生一种改进的工具，用于分子电子结构的电子表征。

The chemical identification of nanometer sized features and individual molecules on solid surfaces is the focus of this research project. With the support of the Analytical and Surface Chemistry Program, Professor Hipps and his colleagues at Washington State University, are using orbital mediated tunneling spectroscopy in combination with scanning tunneling microscopy to examine the electronic structure of large organic and organometallic molecular layers on metal and graphite surfaces. The role of intermolecular packing and interface structure in determining the electronic transport properties of these layers is being examined. The information gained from these studies will provide fundamental design information for molecule based electronic and opto-electronic devices. As electronic devices shrink to the nanoscale and molecular scale, more fundamental information about the electronic structure of these molecular electronic devices is needed. This research project, in the laboratory of Professor Hipps at Washington State University, uses orbital mediated tunneling spectroscopy to obtain this electronic structure information about well characterized molecular overlayers on metal and carbon surfaces. In addition to the fundamental understanding obtained by these studies, an improved tool for the electronic characterization of molecular electronic architectures will result.
