Organic semiconductors are becoming a very powerful electronic technology for applications in flexible displays and low-cost printed circuits. Their charge transport physics and ultimate performance limits are however not well understood. The objective of the proposed project is to establish an intense collaboration between the Osaka and Cambridge organic electronic groups in order to arrive at an in-depth understanding of the relationship between the device physics of conjugated polymers and molecular crystals. We will perform a broad range of directly comparable experiments on the two systems using techniques that are already available in the Osaka and Cambridge groups to understand similarities and differences in the charge transport physics of the two systems. This will include performing the first Hall effect and magnetoresistance measurements on high-mobility polymer semiconductors to compare with measurements already performed in Osaka on molecular crystals. A particularly interesting question is that of polaronic relaxation processes in molecular crystals, and we will perform the first spectroscopic measurements of charge-induced optical absorptions in molecular crystals and compare with those already performed on polymers in Cambridge. The core of the research work outlined above will be carried out by two PhD students, one registered in Cambridge, the other one registered in Osaka. Both students will interact with each other very closely, and will spend significant time during their PhD working in the other location. The two PhD students working on the project will have available the widest possible spectrum of experimental characterisation techniques, and the project will provide an excellent training environment for them to become leaders in future UK-Japan research collaborations.

有机半导体正在成为一种非常强大的电子技术，用于在柔性显示器和低成本印刷电路中应用。但是，他们的电荷运输物理和最终性能限制尚不清楚。拟议项目的目的是建立大阪和剑桥有机电子基团之间的强烈合作，以便深入了解共轭聚合物和分子晶体的设备物理之间的关系。我们将使用在大阪和剑桥组中已经可用的技术对这两个系统进行广泛的直接比较实验，以了解这两个系统的电荷传输物理学的相似性和差异。这将包括对高运动聚合物半导体进行第一厅效应和磁化测量，以与大阪对分子晶体的测量进行比较。一个特别有趣的问题是分子晶体中的二极化弛豫过程，我们将对分子晶体中电荷诱导的光吸收的第一光谱测量，并与剑桥中的聚合物进行比较。上面概述的研究工作的核心将由两名博士生进行，其中一名在剑桥注册，另一位在大阪注册。两个学生都将非常紧密地互动，并将在其他位置工作的博士学位期间花费大量时间。从事该项目的两位博士学位学生将获得最广泛的实验表征技术范围，该项目将为他们提供出色的培训环境，使他们成为未来英国 - 日本研究合作的领导者。
