Purchase of Electron Microscope for Teaching Laboratories

我们将用他们用ILI资助获得的透射电子显微镜为高年级本科生固体物理实验室课程开发一些新的实验。物理系以前不存在这样的仪器，因此不允许将微观结构研究纳入教学实验室课程。瞬变电子显微镜的提供使实验室教师能够强调固体物质中晶格结构和电子性质之间关系的重要性。这些实验展示了现代固体物理中的一些重要现象，包括原子晶格成像、电子的量子干涉、电荷密度波和准晶体衍射。该仪器既可用于成像模式，也可用于互易空间模式，也可用于现代物理课程，演示电子的波动性质和原子结构。此外，该设备还可用于固体物理学的本科生研究项目。正在编写一本实验室手册和参考资料书，以使其他本科生可以访问这些新的实验。

We are to developing a number of new experiments for the senior-year undergraduate Solid State Physics Laboratory course with the transmission electron microscope (TEM) they have acquired with ILI grant funds. Such an instrument did not previously exist in the Physics Department and this did not permit the inclusion of microstructural studies in the teaching laboratory curriculum. The provision of the TEM allows laboratory instructors to emphasize the importance of the relationship between lattice structure and electronic properties in the solid state of matter. The experiments demonstrate a number of important phenomena in modern solid state physics including atomic lattice imaging, quantum interference of electrons, charge density waves, and quasi- crystal diffraction. The instrument is being used in both imaging and reciprocal space modes and is available also for Modern Physics course demonstrations of the wave nature of electrons and atomic structure. The equipment, in addition, is available for undergraduate research projects in solid state physics. A laboratory manual and resource book is being written to make the new experiments accessible to other undergraduate programs.
