Surface Experiments in the Undergraduate Curriculum

9452127莱昂斯我们建议购买一台扫描隧道显微镜/原子力显微镜，用于本科生课程。与科学日益增长的跨学科性质相一致，这些设备将同时供化学系和物理系使用。大多数使用将在高级化学和物理课程中使用，但该仪器将进行演示，该仪器的图像也将在化学和物理入门课程中展示。直到最近，表面表征仪器的高昂费用和维护要求一直让本科院校望而却步。STM/AFM技术的改进降低了数据获取和维护成本，允许小型大学的本科生在环境条件下对样品进行实验。

9452127 Lyons We propose to purchase a scanning tunneling microscope (STM)/atomic force microscope (AFM) instrument for use in the undergraduate curriculum. Consistent with the increasing interdisciplinary nature of science, the equipment will be used by both the chemistry and physics departments. Most of the use will be in advanced chemistry and physics courses, but the instrument will be demonstrated and images from the instrument will be presented in introductory chemistry and physics lectures also. Until recently, the high expense and maintenance requirements of surface characterization instruments have put them out of the reach of undergraduate colleges. Improvements in STM/AFM technology have reduced data acquisition and maintenance costs, allowing undergraduates at small colleges to perform experiments on samples under ambient conditions.
