Stationary and Time-Resolved Luminescence of Organic-Dye/transition metal dichalcogenide Heterostructures — •Julian Schröer, Tim Völzer, Alina Schubert, Rico Schwartz, Stephan Lochbrunner, and Tobias Korn — University of Rostock, Institute of Physics

Thin layers of organic molecules and layered semiconductors build a new compound material with manifolds of interesting applications. The optoelectronic properties of these heterostructures strongly depend on the chosen compounds. Via stationary and time-resolved photoluminescence experiments, we investigate samples of Perylene-Orange (PO) deposited on top of single-layer tungsten diselenide. This joint material exhibits a type-II band alignment, enabling charge transfer processes between the two material layers. Here, we aim to reveal the temperature dependent dynamics of the charge transfer processes. Our work paves the way for a deeper understanding of organic/inorganic heterointerfaces and the functionalization of organics and TMD's in optoelectronic devices.
