Exciton Transfer at Heterointerfaces of MoS₂ Monolayers and Fluorescent Molecular Aggregates.

ABSTRACT: Integration of distinct materials to form heterostructures enables the proposal of new functional devices based on emergent physical phenomena beyond the properties of the constituent materials. The optical responses and electrical transport characteristics of heterostructures depend on the charge and exciton transfer (CT and ET) at the interfaces, determined by the interfacial energy level alignment. In this work, heterostructures consisting of aggregates of fluorescent molecules (DY1) and 2D semiconductor MoS₂ monolayers are fabricated. Photoluminescence spectra of DY1/MoS₂ show quenching of the DY1 emission and enhancement of the MoS₂ emission, indicating a strong electronic interaction between these two materials.
