Scanning Tunneling Microscope for Undergraduate Experiment and Demonstrations

我们已经获得了一台扫描隧道显微镜（STM），供本科生在有监督的实验室课程、课堂演示和本科生独立研究项目中使用。STM为学生介绍材料物理学和我们世界的基本量子力学性质提供了新的、更好的方法。然而，由于STM技术是相当新的，它在物理和化学课程中的应用是非常罕见的。我们正在利用STM的教学潜力，将其整合到我们的本科课程中。我们正在从三个具体方面初步实施这一计划。首先，我们介绍了一套定量的STM实验，用于我们的高级实验实验课程。我们正在设计一个实验部分，让学生探索量子力学隧道，并学习如何使用它来研究材料的性质。其次，我们正在开发两个课堂演示，分别使用STM来说明表面和分子的原子结构。第三，我们正在开发STM的潜力，为本科生提供高质量的实践研究经验，计划在本科生独立研究项目中使用STM。我们认为，尽快将现代研究成果带入课堂是很重要的。我们正在将分子成像和操作的新领域整合到我们的课程中，让学生对我们的物理世界和现代技术的基本原理有更具体的了解。＊＊＊

9351910 Rogers We have acquired a scanning tunneling microscope (STM) for use by undergraduates in supervised laboratory course work, in classroom demonstrations and for scheduled use in undergraduate independent research projects. The STM offers new and dramatically better ways to introduce students to the physics of materials and to the basic quantum mechanical nature of our world. However, because the STM technique is quite new, its use in physics and chemistry courses is extremely rare. We are harnessing the instructional potential of STM by integrating it into our undergraduate curriculum. We are initially implementing this plan in three specific ways. First, we introduce a set of quantitative STM experiments for use in our senior level experimental laboratory course. We are designing a laboratory section in which the students explore quantum mechanical tunneling and learn how it can be used to study the properties of materials. Second, we are developing two classroom demonstrations which use the STM to illustrate the atomic structure of surfaces and molecules respectively. Third, we are tapping the potential of STM for high quality hands-on research experience for undergraduates by scheduling the use of the STM for undergraduate independent research projects. We believe that it is important to bring modern research results into the classroom as soon as it is practical to do so. We are integrating the new field of molecular imaging and manipulation into our curriculum to give students a more concrete understanding both of our physical world and the fundamental principles underlying modern technology. ***
