Spectroscopy of Single Molecules at Specific Sites on Surfaces

该项目由分析和表面化学项目支持，旨在开发和实施一种新的表面分析方法，该方法结合了扫描隧道显微镜和轨道介导隧道光谱。华盛顿州立大学化学系的Hipps教授和他的学生将致力于扩展这项技术的能力。该方法允许在导电衬底上对纳米尺寸的特征进行化学表征。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。在完成仪器开发后，将对酞菁分子与石墨衬底的相互作用进行研究，以充分验证这里开发的方法的基本思想。在化学上识别纳米尺寸表面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设备制造。这个研究项目结合了经过良好测试的扫描隧道显微镜方法和一种新开发的称为轨道介导隧道光谱的方法，制造了一种可以提供这类信息的仪器。这种方法的可用性应该对一系列与表面有关的技术产生广泛的影响。

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.
