%X The exciton, a quasiİ\particle that creates a bound state of an electron and a hole, is typically found in semiconductors. It has attracted major attention in the context of both fundamental science and practical applications. Transition metal dichalcogenides (TMDs) are a new class of 2D materials that include direct bandİ\gap semiconductors with strong spin¨Corbit coupling and manyİ\body interactions. Manipulating new excitons in semiconducting TMDs could generate a novel means of application in nanodevices. Here, the observation of highİ\energy excitonic peaks in the monolayerİ\MoS2 on a SrTiO3 heterointerface generated by a new complex mechanism is reported, based on a comprehensive study that comprises temperatureİ\dependent optical spectroscopies and firstİ\principles calculations. The appearance of these excitons is attributed to the change in manyİ\body interactions that occurs alongside the interfacial orbital hybridization and spin¨Corbit coupling brought about by the excitonic effect propagated from the substrate. This has further led to the formation of a Fermiİ\surface feature at the interface. The results provide an atomicİ\scale understanding of the heterointerface between monolayerİ\TMDs and perovskite oxide and highlight the importance of spin¨Corbit¨Ccharge¨Clattice coupling on the intrinsic properties of atomicİ\layer heterostructures, which open up a way to manipulate the excitonic effects in monolayer TMDs via an interfacial system
