Präparationskammer (MVD/PVD) mit XPS/UPS, STM/AFM und LEED

我们小组的研究重点是原子薄二维(2D)材料的材料科学和应用，包括有机单分子膜、碳纳米膜、石墨烯、相关的2D片材及其范德华异质结构。材料科学方面包括从分子前体通过自组装、电子辐照和温度诱导修饰、化学官能化等方法生长具有定制性能的材料；表征生长机制、结构和电子性质，精确到原子尺度。基于这一互补分析，我们将工程材料应用于功能器件，包括场效应器件、纳米过滤器和生物活性纳米膜。为了进行这项研究，将XPS、UPS、AFM、STM、KPFM、LEED等互补的原位表面科学/纳米结构分析技术与有机化合物和金属的PVD、离子溅射和变温电子辐照等制备技术相结合是绝对必要的。因此，在本方案中，我们将这些技术集成到一个交钥匙超高压多探头(MP)系统。MP系统将是我们在FSU耶拿新成立的“应用物理化学和分子纳米技术”小组的主要研究仪器。此外，它还将为FSU Jena从事纳米材料物理和化学研究的其他小组提供一种全新的最先进的材料科学研究的可能性，包括薄层、纳米线和纳米颗粒。

The research of our group is focused on materials science and applications of atomically thin two-dimensional (2D) materials including organic monolayers, carbon nanomembranes, graphene, related 2D sheets and their van der Waals heterostructures. The materials science aspects include growth of these materials with tailored properties from molecular precursors via self-assembly, electron irradiation and temperature induced modification, chemical functionalization; characterization of the growth mechanisms, structural and electronic properties down to the atomic scale. Based on this complementary analysis we implement the engineered materials in functional devices including field-effect devices, nanofilters and bioactive nanomembranes. To enable this research, application of complementary in situ surface science/nanostructure analytic techniques such as XPS, UPS, AFM, STM, KPFM, LEED in combination with preparative techniques such as PVD of organic compounds and metals, ion sputtering and electron irradiation at variable temperatures is absolutely necessary. Therefore, we apply in this proposal for a turnkey UHV Multiprobe (MP)-System in which these techniques are integrated. The MP-System will be the major research instrumentation of our newly established group of "Applied Physical Chemistry & Molecular Nanotechnology" at the FSU Jena. Moreover it will provide a qualitatively new state-of-the-art possibility for materials science research for other groups at the FSU Jena working on physics and chemistry of nanomaterials including thin layers, nanowires and nanoparticles.
