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

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

Objectives

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.
