The Institute of Micro- and Nanostructure Research runs the electron microscopy laboratory in the Center for Nanoanalysis and Electron Microscopy which constitutes the central facility for nanocharacterization of the Friedrich-Alexander University Erlangen-Nürnberg. The laboratory comprises, among other instruments, a state-of-the-art focused ion beam scanning electron micrsocope and a cutting-edge double-corrected transmission electron micrsocope.The instruments are extensively used to study the microscopic structure as well as structure-property relationships of functional and structural materials in a variety of research projects including a Research Training Group, two Collaborative Research Centers, two Priority Programs and the Excellence Initative. In order to further extend and fully employ the capabilities of the existing instruments for materials characterization a modern electron backscattered diffraction system has to be attached to the existing focused ion beam instrument. The system enables crystallographic investigation of materials including orientation mapping of polycrystals at the micro and nanoscale. Because of the high relevance of this information for the research carried out in Erlangen the electron backscatter diffraction system will be extensively used with all its modes. Fields of application include the site-specific preparation of samples for transmission electron microscopy and mechanical testing, strain mapping and three-dimensional analysis of crystal phases (by combination with the existing energy dispersive X-ray spectroscopy system and slice-and-view tomography). The compatible in situ heating stage will be used to study dynamical processes at elevated temperatures, like, e.g. texture evolution during grain growth and dewetting. The in situ investigation of such dynamical processes constitutes a research focus in Erlangen and, in particular, in the Research Training Group "In situ microscopy with electrons, X-rays and scanning probes".

微观和纳米结构研究所在纳米分析和电子显微镜中心运行电子显微镜实验室，该中心构成了埃尔朗根-恩<s:1>伦贝格大学纳米表征的中心设施。除其他仪器外，该实验室还包括最先进的聚焦离子束扫描电子显微镜和最先进的双校正透射电子显微镜。这些仪器被广泛用于研究微观结构以及功能和结构材料的结构-性能关系，在各种研究项目中，包括一个研究训练组，两个合作研究中心，两个优先项目和卓越计划。为了进一步扩展和充分利用现有材料表征仪器的能力，必须在现有的聚焦离子束仪器上附加一个现代电子背散射衍射系统。该系统能够对材料进行晶体学研究，包括在微纳米尺度上对多晶体进行定向测绘。由于这些信息对在埃尔兰根进行的研究具有高度的相关性，电子背散射衍射系统将被广泛地应用于其所有模式。应用领域包括用于透射电子显微镜和力学测试的特定地点的样品制备，应变映射和晶体相的三维分析（结合现有的能量色散x射线光谱系统和切片-视图断层扫描）。相容性原位加热阶段将用于研究高温下的动态过程，如晶粒生长和脱湿过程中的织构演变。对这种动态过程的现场调查是埃尔兰根的一个研究重点，特别是“用电子、x射线和扫描探针进行现场显微镜观察”的研究培训小组。
