The aim of this application is to substantially strengthen green energy research at the University of Freiburg by implementation of a new pole of competence. It is intended to install an atom probe tomography instrument (APT) and a focus-ion-beam/scanning electron microscopy (FIB-SEM) system. The University of Freiburg ranks ninth among German universities in terms of the acquisition of third-party funding from the German Research Foundation, but APT is not available yet, which hampers research in many fields of science. ‘Correlative Microscopy’ will be set up by combining FIB-SEM and APT with the APT as the main instrument. The main use of Correlative Microscopy will be the research on energy devices such as solar cells and batteries. Cross-scale correlative microscopy will make significant contributions to understanding physical phenomena (interdiffusion, segregation, precipitation, and phase formation in the bulk and at internal interfaces) down to the atomic level. This is critical to further improve the efficiency of solar cells and batteries. Other areas of application will include perovskites, multi-material-joints like welded aluminum-steel or aluminum-titanium compounds, semiconductor heterostructure devices, and quantum materials (quantum bits for quantum computers) in collaboration with other groups at the University of Freiburg and Fraunhofer Institutes.

该应用的目的是通过安装原子探针断层扫描仪（APT）和聚焦离子束/扫描电子显微镜来大幅加强弗莱堡大学的绿色能源研究。弗莱堡大学在获得德国研究基金会第三方资助方面在德国大学中排名第九，但尚未获得APT，这阻碍了许多科学领域的研究。将FIB-SEM和APT结合起来建立“相关显微镜”，以APT为主要仪器，相关显微镜的主要用途将是对太阳能电池和电池等能源的研究，这将具有重大意义。有助于理解原子水平的物理现象（相互扩散、偏析、沉淀和相形成），这对于进一步提高太阳能电池和电池组的效率至关重要。与弗莱堡大学和弗劳恩霍夫研究所的其他小组合作，应用将包括钙钛矿、多材料接头（如焊接铝钢或铝钛化合物）、半导体异质结构器件和量子材料（量子计算机的量子比特）。
