Local electronic structure and charge transport dynamics in organic films and interfaces by means of inner-shell excitation

有机薄膜和界面的电子结构对有机器件如发光二极管、场效应晶体管和光伏电池的性能起着至关重要的作用。这些设备的功能是占主导地位的几何膜/界面结构，这取决于分子结构和样品制备。在这项工作中，我们成功地澄清了有机薄膜和界面的几何和电子结构之间的相关性，通过（i）的几何膜/界面结构的控制和（ii）本地电子结构分析的基础上软X射线光谱。

The electronic structure of organic thin films and interfaces plays a crucial role in the performance of organic devices such as light-emitting diodes, field-effect transistors, and photovoltaic cells. The functionality of these devices is dominated by the geometric film/interface structure, which varies depending on the molecular structure and the sample preparation. In this work, we succeeded to clarify the correlation between the geometric and electronic structure of organic thin films and interfaces by means of the combination of (i) the control of geometric film/interface structure and (ii) local electronic structure analyses based on soft X-ray spectroscopies.
