As electronic component miniaturization progresses, innovative materials and their unique interactions become pivotal to the ongoing evolution of semiconductor devices. Transition metal dichalcogenides (TMDCs), such as molybdenum disulfide (MoS2), have gained significant attention in this context. These materials possess a layered crystal structure, tunable bandgaps and high carrier mobilities, making them especially appealing for use in optoelectronics, photovoltaics and field-effect transistors. To further refine these semiconductor components for targeted applications, merging TMDCs with organic semiconductors is a promising strategy, also because it preserves the structural integrity of the TMDCs. Past endeavors in this direction have involved functionalization with strong electron acceptors such as (fluorinated) tetracyanoquinodimethane (TCNQ) , fluorinated fullerenes , and 4-nitrobenzenediazonium tetrafluoroborate (4-NBD) , all of which induce p-type doping of the TMDC by integer charge transfer. Similarly, n-doping has been achieved through functionalization with different organic and inorganic heterostructures. A large portion of research was dedicated to mono-and few-layer TMDCs and there are few studies that deal with bulk crystals and even less with heterostructures. Given that the number of layers is crucial for the properties of the electronic structure, expanding the research to bulk crystals is necessary to gain a deeper understanding of heterostructures from organic molecules and TMDCs.
