Presidential Young Investigator Award: UHV Scanning Tunneling Microscopy

使用扫描隧道显微镜将研究表面上的单分子和分子复合物的化学、键合、结构和动力学。这些研究将使用一种在无振动室内的特殊低温超高真空装置。这种设备将特别适用于振动光谱和微观扩散速率的研究。该研究还将利用绝缘材料的微波频率介电特性来研究绝缘材料。这项为期五年的持续拨款给宾夕法尼亚州立大学，以支持Weiss教授作为总统青年研究员，旨在促进他在扫描隧道领域快速有效地成长为一名独立研究员显微镜。在分析和表面化学的一般领域，研究重点是评估潜在的应用和开发新的应用，扫描隧道显微镜使用一种新的超高真空设备。可以预见，表面化学的理解及其在材料科学中的应用将取得重大进展。

The chemistry, bonding, structure and dynamics of single molecules and molecular complexes on surfaces will be investigated using scanning tunneling microscopy. A special low temperature ultra-high vacuum apparatus in a vibration free room will be used for these studies. This equipment will be especially appropriate for a study of vibrational spectra and microscopic diffusion rates. The investigation will also study insulating materials by exploiting their microwave frequency dielectric properties. %%% This five year continuing grant to Pennsylvania State University for support of Professor Weiss as a Presidential Young Investigator is designed to promote his rapid and effective growth as an independent researcher in the area of Scanning Tunneling Microscopy. The research, in the general area of Analytical and Surface Chemistry, focuses on evaluating the potential applications and developing new applications for scanning tunneling microscopy by using a novel ultra-high vacuum apparatus. Important developments in the understanding of surface chemistry and its application to materials science can be anticipated.
