The Department of Chemistry will acquire a Scanning Tunneling Microscope (STM) for undergraduate education. The project intends the incorporation of STM into the junior and senior years of the undergraduate chemistry curriculum at the University of Miami. STM is a conceptually and instrumentally simple technique which has developed from an esoteric research topic at the beginning of this decade to a highly useful tool in the field of surface science at present. STM is capable of generating surface images with atomic resolution and thus affords the direct observation of individual atoms. STM can also be utilized for microscopic purposes competing advantageously with Transmission Electron Microscopy and Scanning Electron Microscopy. STM instruments are completely computerized and easy to use. This technique will be used to introduce undergraduate students to the growing field of surface chemistry. This project will pioneer the incorporation of STM into upper level chemistry laboratories in undergraduate courses of Instrumental Analysis and Physical Chemistry.

化学系将购置一台扫描隧道显微镜（STM）用于本科教学。该项目打算将STM纳入迈阿密大学本科化学课程的三年级和四年级。STM是一种概念和仪器简单的技术，从本世纪初的一个深奥的研究课题发展到目前表面科学领域的一个非常有用的工具。STM能够产生具有原子分辨率的表面图像，从而提供对单个原子的直接观察。STM也可以用于显微镜目的，与透射电子显微镜和扫描电子显微镜竞争优势。STM仪器完全电脑化，易于使用。这项技术将用于向本科生介绍表面化学的发展领域。本项目将率先在仪器分析和物理化学本科课程的高级化学实验室中引入STM。
