To harness the unique characteristics of monolayer TMD due to many-body interactions, it is essential to fine adjust the materials' electro-optical properties and to transfer these distinct traits to other materials. One economical and efficient approach is to create heterojunctions, including TMD-TMD and molecule-TMD heterojunctions. For example, it was recently shown that many-body control of electron localization in moiré heterostructures can greatly improve catalytical performance . Similarly, doping monolayer TMD with molecules could control interfacial band alignment and its chemical and electrostatic environments . In the meantime, due to the relatively weak screening along the normal direction of the interfaces, the heterojunction could potentially inherit the electronic properties of monolayer TMDs. For example, the general existence of interfacial charge transfer (CT) excitons in molecule-TMD heterojunctions can enable the electronic structure hybridization between TMD and molecules. Recently, CT trions, also referred as interlayer trions, were also observed in TMD/TMD heterojunctions, offering another route to control and transfer electronic properties across the heterojunctions. Given the analogous nature of the two layers in TMD/TMD heterojunctions, it is a pertinent question to ask whether the strong many-body interactions specific for CT trion formations can persist under the influence of a dramatically different charge acceptor, such as molecules with localized wavefunctions, when molecules and monolayer-TMD form heterojunctions. Realizing CT trions in monolayer-TMD heterojunctions may enable transfer specific attributes TMD trions in TMD to the surface molecular species, which include spin polarizations to enable spin-polarized chemistry and the in-plane delocalization which facilitates charge hopping among molecular sites., may transfer In return, the surface molecules could dynamically modify these electronic characteristics in TMD through CT trions, for photonics, optoelectronic and valleytronic applications.
