Spectroscopy of Single Molecules at Specific Sites on Surfaces

该项目在分析和表面化学计划的支持下，旨在开发和实施一种新的表面分析方法，该方法将扫描隧道显微镜与轨道介导隧道光谱相结合。 华盛顿州立大学化学系的希普斯教授和他的学生将致力于扩展这种技术的能力。 该方法允许在导电衬底上的纳米尺寸特征的化学表征。 这种方法在电子器件制造，催化，分子电子学和表面科学领域的应用是可能的。 在仪器开发完成后，将对酞菁分子与石墨基底的相互作用进行研究，以充分测试这里开发的方法的基本思想。化学识别表面纳米尺寸特征的能力对于发展对许多技术重要过程的理解至关重要，例如多相催化和电子器件制造。 该研究项目结合了经过测试的扫描隧道显微镜方法和新开发的称为轨道介导隧道光谱的方法，以制造可以提供这种信息的仪器。 这种方法的可用性应在一系列表面相关技术中产生广泛影响。

This project, supported in the Analytical and Surface Chemistry Program, is directed towards the development and implementation of a new surface analysis method that combines scanning tunneling microscopy with orbital mediated tunneling spectroscopy. Professor Hipps and his students in the Department of Chemistry at Washington State University will work to extend the capabilities of this technique. This method allows the chemical characterization of nanometer sized features on conducting substrates. Applications of this methodology in the fields of electronic device fabrication, catalysis, molecular electronics, and surface science are likely. Following completion of the instrument development, investigation of the interaction of phthalocyanine molecules with graphite substrates will be carried out to fully test the ideas underlying the method developed here.The ability to chemically identify nanometer sized features on surfaces is crucial to developing an understanding of a number of technologically important processes such as heterogeneous catalysis and electronic device fabrication. This research project combines the well tested method of scanning tunneling microscopy with a newly developed method known as orbital mediated tunneling spectroscopy to make an instrument that can provide this sort of information. The availability of such a method should have widespread impact in a range of surface related technologies.
