The functionality of organic semiconductor thin film devices depends in most cases to a significant way on the microstructure of the film and the orientation of the molecules. One the one hand, this poses a challenge on the field, on the other hand, the ability to combine materials with very different functional and structural properties in a single device is unique to molecular systems and presents a wealth of opportunities that have so far not been fully exploited.The goal of this project is to investigate the microstructure of molecular blends and to find ways to obtain regimes favouring isolated molecules, superstructures and phase separated domains. The application focus is on molecular spintronics and organic solar cells, given similar material systems and characterisation techniques, but different microstructural requirements. The PhD student will be able to employ a range of unique in-situ and ex-situ characterisation techniques to determine the microstructure during thin film growth and post-deposition to correlate microstructure with device properties.Given the close connection of microstructure and device performance for many organic electronics devices, we see many synergies with other PE-CDT research projects and areas of research in organic electronics, as well as high relevance for industry partners.

有机半导体薄膜器件的功能性在大多数情况下取决于薄膜的微观结构和分子的取向。一方面，这对该领域提出了挑战，另一方面，将具有非常不同的功能和结构特性的联合收割机材料组合在单个设备中的能力是分子系统所独有的，并且提供了大量迄今尚未充分利用的机会。超结构和相分离域。应用的重点是分子自旋电子学和有机太阳能电池，给出类似的材料系统和表征技术，但不同的微观结构要求。博士生将能够采用一系列独特的原位和非原位表征技术来确定薄膜生长和沉积后的微观结构，以将微观结构与器件性能相关联。鉴于许多有机电子器件的微观结构和器件性能密切相关，我们看到了与其他PE-CDT研究项目和有机电子研究领域的许多协同作用，以及与行业合作伙伴的高度相关性。
