Glovebox-Evaporator Cluster System

能源的可持续生产、转化和储存仍然是一项重大的全球挑战。新型功能能源材料的发现是解锁下一代技术设计的新概念和功能的关键。这样的突破依赖于对非常干净的材料的研究，这些材料是通过明确的合成制造出来的，从而揭示了材料的内在特性。该小组目前的重点是可溶液加工的混合金属卤化物钙钛矿，它已成为光电子和有机半导体领域有前途的多晶半导体。这些高度可调的系统可以通过基于低温溶液的方法加工成薄膜，这使得它们特别适合应用。定义良好的新型材料对我们的先进光谱方法至关重要，例如瞬态光致发光，瞬态吸收或先进的多维光谱，以及高分辨率光学全息和近场显微镜。这些技术从相杂质和缺陷中提取出很小的贡献，这将掩盖固有的电子、化学和结构特性。结合我们在材料表征和最先进的光谱学方面的专业知识，我们的目标是在以下领域取得突破：i)光子应用的手性混合半导体；ii)信息技术的磁性混合材料；iii)储能材料的混合电子-离子动力学；iv)光-物质相干相互作用的控制。因此，新型有机/杂化材料系统的合成，以及与应用相关的接触和多层结构，必须在惰性条件下进行，不包括氧气和水，以避免引入缺陷，杂质和无序。这样的条件只能在手套箱中实现，手套箱提供必要的清洁和可重复的制造条件，具有低水平的氧气和水含量，以及清洁的气体气氛。因此，我们在此寻求资金用于合成和加工新型混合和有机半导体的集成手套箱-蒸发器集群。手套箱系统将为我们的材料发现提供多功能制造，从基于溶液的薄膜加工与旋转涂层到单晶的生长。更重要的是，一个基于溶液的合成和热蒸发的集成系统是可用的，这样就可以在不污染界面或材料表面的情况下制造完整的光子和接触多层系统，从而成功表征光子结构和器件中能量材料在操作条件下的激发动力学。

Sustainable generation, transformation and storage of energy remains a major global challenge. The discovery of novel functional energy materials is key for unlocking novel concepts and functions for the design of next-generation technologies. Such break-throughs rely on investigations of very clean materials that are fabricated from well-defined synthesis, so that the intrinsic material properties are revealed. A current focus in the group are the solution-processable hybrid metal-halide perovskites, which have emerged as promising polycrystalline semiconductors for optoelectronics, and organic semiconductors. These highly-tunable systems can be processed into thin films by low-temperature solution-based methods, which makes them particularly suitable for applications. Well-defined novel materials are further critical for our advanced spectroscopic methods, such as transient photoluminescence, transient absorption or advanced multi-dimensional spectroscopy, as well as high-resolution optical holographic and nearfield microscopy. These techniques pick up even small contributions from phase-impurities and defects, which would obscure the intrinsic electronic, chemical and structural properties. Combining our expertise in material characterization and state-of-the-art optical spectroscopy we aim for breakthroughs to advance material functionality in the areas of i) Chiral hybrid semiconductors for photonic applications ii) Magnetic hybrid materials for information technologies iii) Mixed electron-ionic dynamics of energy storage materials and iv) Control of coherent light-matter interactions. Thus, synthesis of novel organic/hybrid material systems, also in contacted and multilayer structures relevant for applications, must occur under inert conditions, excluding oxygen and water, to avoid introducing defects, impurities and disorder. Such conditions can only be achieved in gloveboxes which provide the necessary clean and reproducible fabrication conditions with low levels of oxygen and water content, and clean gas atmosphere. Thus, we here seek funding for an integrated glovebox-evaporator cluster for synthesis and processing of novel hybrid and organic semiconductors. The glovebox system will provide versatile fabrication for our materials discovery, ranging from solution-based thin film processing with spin-coating to growth of single-crystals. It is further crucial that an integrated system of solution-based synthesis and thermal evaporation is available, so that fabrication of complete photonic and contacted multilayer systems can be achieved without contaminating interfaces or material surfaces, for successful characterization of excitation dynamics in photonic structures and of energy materials in devices under operating conditions.
