Surface Experiments in the Undergraduate Curriculum

9452127 Lyons我们建议购买一台扫描隧道显微镜(STM)/原子力显微镜（AFM）仪器用于本科课程。随着科学跨学科性质的增加，这些设备将被化学和物理系同时使用。大部分使用将在高级化学和物理课程中，但仪器的演示和图像也将在化学和物理入门课程中呈现。直到最近，表面表征仪器的高费用和维护要求使它们超出了本科院校的能力。STM/AFM技术的改进降低了数据采集和维护成本，使小型学院的本科生能够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.
