本课题组的研究重点是材料科学和原子级薄二维（2D）材料的应用，包括有机单层，碳纳米膜，石墨烯，相关的二维片及其货车德瓦尔斯异质结构。材料科学方面包括通过自组装，电子辐照和温度诱导改性，化学功能化从分子前体中生长具有定制特性的这些材料;表征生长机制，结构和电子性能下降到原子尺度。基于这种互补的分析，我们实现了工程材料的功能器件，包括场效应器件，纳米过滤器和生物活性纳米膜。为了使这项研究，应用互补的原位表面科学/纳米结构分析技术，如XPS，UPS，AFM，STM，KPFM，LEED结合制备技术，如PVD的有机化合物和金属，离子溅射和电子辐照在可变温度是绝对必要的。因此，我们申请在这个建议交钥匙特高压多探头（MP）系统，其中这些技术是集成的。MP系统将成为我们在FSU Jena新成立的“应用物理化学与分子纳米技术”组的主要研究仪器。此外，它将为FSU Jena的其他小组提供材料科学研究的新的最先进的可能性，这些小组致力于纳米材料的物理和化学，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.
