Ultra High Vacuum Techniques and Experimentation in Materials Science

超高真空（UHV）技术正在成为材料和表面问题研究的标准。该项目将开发一个高质量的特高压设备，这样高露洁就可以将这些重要的技术和材料科学问题的经验引入他们的高层实验室项目。他们打算在实验方法课程中加入一个精心监督的训练模块，提供实验练习来支持固态物理课程，并将该系统用作高级实验室计划的主要站点。此外，在材料和表面科学方面有许多研究问题，这些问题可以由有才华的本科生作为独立项目来完成。该项目的基础是一个带有不锈钢试验室的特高压系统，该试验室可以配置为接受各种实验。附加功能包括：(1)离子溅射枪，使表面原子清洁；(2)残余气体分析仪，以支持特高压技术的培训计划，并从表面进行气体解吸实验；(3)通过蒸发制备高质量薄膜的手段；(4)反射高能电子衍射系统，以原位研究制备的薄膜的结构，并使电子衍射实验成为可能。

Ultra high vacuum (UHV) techniques are becoming standard for the study of materials and surface problems. This project will develop a high quality UHV facility so that Colgate can introduce training in these important techniques and experience with materials science problems into their upper level laboratory program. They intend to incorporate a carefully supervised training module into the experimental methods course, provide experimental exercises to support the Solid State Physics course, and use the system as a major station in the advanced laboratory program. In addition, there is a wide range of research problems in materials and surface science that are manageable for talented undergraduates to accomplish as independent projects. The basis for the project is a UHV system with a stainless steel test chamber that can be configured to accept a variety of experiments. Additional features to be incorporated are: (1) an ion sputter gun to get surfaces atomically clean, (2) a residual gas analyzer to support the training program in UHV techniques, and to do experiments in desorption of gasses from surfaces, (3) a means to prepare high quality thin films by evaporation, and (4) a reflection high energy electron diffraction system to investigate the structure of prepared films in situ, and make possible electron diffraction experiments.
