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.

我们将使用他们用 ILI 赠款资金购买的透射电子显微镜 (TEM) 为高年级本科生固体物理实验室课程开发一些新实验。 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实验室教学课程。 TEM 的提供使实验室讲师能够强调固态物质中晶格结构和电子特性之间关系的重要性。 这些实验展示了现代固体物理学中的许多重要现象，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。该仪器可用于成像和倒易空间模式，也可用于现代物理课程演示电子和原子结构的波动性质。 此外，该设备还可用于固体物理学的本科研究项目。 正在编写实验室手册和资源书，以使其他本科课程能够使用新实验。
