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.

该项目由分析和表面化学计划资助，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中介隧道光谱。希普斯教授和他在华盛顿州立大学化学系的学生将致力于扩展这项技术的能力。这种方法允许对导电基板上的纳米级特征进行化学表征。这种方法有可能在电子器件制造、催化、分子电子学和表面科学等领域得到应用。在仪器开发完成后，将对酞菁分子与石墨衬底的相互作用进行研究，以充分测试本文开发的方法背后的想法。从化学上识别表面纳米级特征的能力对于发展对许多重要技术过程的理解至关重要，如多相催化和电子器件制造。这项研究项目将经过充分测试的扫描隧道显微镜方法与一种新开发的称为轨道中介隧道光谱的方法相结合，以制造一种可以提供此类信息的仪器。这种方法的可获得性应该会对一系列与表面有关的技术产生广泛影响。
