Local electronic structure of single molecules and molecular nanostructures coupled to monolayers of transition metal dichalcogenides (A14*)

该项目旨在解决在有机覆盖层与过渡金属二硫属化物（TMDC）单层接触的界面处的能级对准、电荷转移和屏蔽的基本过程。采用扫描隧道显微镜（STM），原子力显微镜（AFM）和它们的相关光谱，我们解决这些属性与原子尺度的分辨率。因此，我们将能够精确地识别屏蔽长度，这是显着大于在二维材料比传统的三维同行。此外，我们将探测和创建单个缺陷，并研究它们如何局部修改附着分子的能级排列。

This project aims at resolving fundamental processes of energy level alignment, charge transfer and screening at the interface of an organic overlayer in contact to a monolayer of a transition metal dichalcogenide (TMDC). Employing scanning tunneling microscopy (STM), atomic force microscopy (AFM) and their related spectroscopies we resolve these properties with atomic-scale resolution. Thus, we will be able to precisely identify screening lengths, which are significantly larger in two-dimensional materials than in the traditional three-dimensional counterparts. Furthermore, we will probe and create individual defects and investigate how they locally modify the energy level alignment of attached molecules.
